Hormones play a major role in how your hair grows and how much oil (sebum) your scalp produces. When these hormones are out of balance, they can cause thinning hair, excessive oiliness, or even hair loss. Here's what you need to know:
- Androgens like testosterone and DHT increase sebum production and can shrink hair follicles, leading to hair thinning or loss.
- Estrogen helps maintain healthy hair growth, but lower levels (e.g., during menopause) can make androgen effects worse.
- Thyroid hormones regulate hair growth speed, while imbalances can cause shedding.
- Insulin resistance contributes to higher androgen levels, worsening scalp oiliness and hair loss.
Women are particularly sensitive to hormonal fluctuations, especially during life changes like pregnancy, menopause, or conditions like PCOS. Treatments such as Spironolactone, Minoxidil, and Metformin can help manage these issues by targeting the root hormonal imbalances.
Telehealth platforms like Oana Health offer personalized, prescription-based solutions for addressing hormonal hair loss and excess oil production, making treatment more accessible and convenient.
WHAT CAUSES EXCESS SEBUM PRODUCTION ON THE SCALP?
How Androgens Increase Sebum Production
Androgens act like fuel for sebaceous glands, pushing them to ramp up oil production. This happens through specific biological processes that directly influence the cells responsible for creating sebum.
How Androgens Influence Sebaceous Glands
Sebaceous glands contain androgen receptors, and when hormones like testosterone or DHT bind to these receptors, they kickstart gene activity that enlarges sebocytes and boosts sebum production. Sebocytes, the cells that generate sebum, multiply and become more active under the influence of elevated androgen levels.
In some cases, sebaceous glands can become overly sensitive to androgens. For example, women with conditions like PCOS may experience this heightened sensitivity, where even normal androgen levels can lead to excessive oil production.
Androgens can also increase the size of sebaceous glands. Larger glands naturally produce more oil, creating a feedback loop where continued androgen exposure leads to even bigger glands and higher oil output. This explains why hormonal imbalances can progressively make hair greasier over time.
The Science Behind Androgen Activity
To understand how androgens stimulate sebaceous glands, it’s important to look at the biochemical pathways involved. A key player here is 5α-reductase, an enzyme that converts testosterone into DHT, a hormone about five times more potent at binding to androgen receptors.
There are two types of 5α-reductase: Type I, found in sebaceous glands, and Type II, located in hair follicles. These enzymes enhance local androgen activity by converting testosterone into DHT directly within scalp tissue. This means that even women with normal blood testosterone levels can experience excessive oil production if their scalp has high 5α-reductase activity.
Genetics also play a role. Some women inherit a higher density of androgen receptors in their sebaceous glands, making them more prone to oily scalp conditions. This genetic predisposition helps explain why scalp and hair issues often run in families.
Additionally, insulin-like growth factor-1 (IGF-1) can amplify androgen effects. High insulin levels, often seen in insulin resistance, increase IGF-1 production, which further sensitizes sebaceous glands to androgens, worsening oiliness and related hair problems.
These factors - enzymatic activity, receptor density, and hormonal interplay - set the stage for excessive sebum production and its impact on scalp health.
How Excess Sebum Harms Scalp Health
When sebum production goes into overdrive, it mixes with dead skin cells and clogs hair follicles. This blockage restricts the flow of nutrients, leading to the gradual shrinking of hair shafts. Over time, the affected follicles may produce thinner, weaker hair strands or stop producing hair altogether.
Excess androgens can also alter the composition of sebum, changing its fatty acid profile. This modified sebum is more prone to oxidation, which can trigger inflammation and irritate the scalp, further damaging hair follicles.
Another issue is the overgrowth of Malassezia, a yeast that naturally lives on the scalp and thrives on sebum. When oil production spikes, Malassezia populations can explode, leading to inflammation and conditions like seborrheic dermatitis. This adds even more stress to hair follicles, potentially speeding up hair loss.
Excess sebum also disrupts the scalp’s natural pH balance. Normally, the scalp maintains a slightly acidic pH of 4.5 to 5.5, which supports a healthy environment for hair and skin. But increased oil production can shift the pH toward more alkaline levels, creating a breeding ground for harmful bacteria while beneficial microorganisms struggle to survive.
These insights highlight the importance of addressing the root causes of hormonal imbalances. For women dealing with androgen-driven sebum overproduction, tackling the underlying hormonal issues is key. Oana Health offers personalized telehealth solutions aimed at managing excessive oil production and its impact on hair health.
How Androgens Damage Hair Follicles
Androgens, while responsible for triggering excess sebum production, also directly harm hair follicles. This two-pronged attack results in clogged follicles and direct follicle damage.
Androgen Sensitivity in Hair Follicles
Androgens don’t just increase sebum production - they also weaken hair follicles. Follicles in different parts of the scalp have varying levels of sensitivity to androgens. Those located at the hairline and crown are particularly sensitive, as they contain the highest concentration of androgen receptors. This is why these areas are often the first to show signs of thinning in women experiencing hormonal hair loss.
When the androgen DHT binds to these receptors, it sets off a process known as follicular miniaturization. Over several growth cycles, the hair follicle shrinks. Each time a hair falls out and regrows, the new strand becomes thinner and shorter. Eventually, the follicle produces only fine, colorless vellus hair.
This gradual thinning happens in stages: the hair shaft first loses diameter, then length, until the follicle can no longer support normal hair growth.
Genetics play a major role in determining how sensitive your follicles are to androgens. Women who inherit genes for a higher density of androgen receptors in their scalp follicles are more likely to experience severe hair loss, even if their hormone levels are within a normal range. Interestingly, this genetic predisposition can skip generations, meaning you might inherit it from a grandparent rather than a parent.
Inflammation adds another layer of damage. When androgens bind to follicle receptors, they can trigger inflammatory responses, further weakening the follicles. This inflammation increases stress on already vulnerable roots, speeding up the miniaturization process.
Why Androgens Grow Body Hair But Cause Scalp Hair Loss
The effects of androgens vary depending on the area of the body, which can be confusing for women dealing with hormonal hair changes. While androgens thin scalp hair, they simultaneously promote the growth of facial, chest, and other body hair.
This happens because follicles in different areas respond differently to androgen signals. Scalp follicles - especially those at the hairline and crown - interpret androgen binding as a cue to shrink and slow down. Meanwhile, follicles on the face, arms, and torso respond by growing thicker, longer hair.
The difference lies in the genes activated by androgens. In scalp follicles, androgens activate genes that produce growth-inhibiting proteins and inflammatory molecules. These proteins restrict blood flow and nutrient delivery to the follicle. On the other hand, facial follicles activate genes that encourage cell division and increase the diameter of the hair shaft.
The depth of the follicle also plays a role. Scalp follicles are deeper and more complex than body hair follicles, making them more susceptible to hormonal disruption. Body hair follicles, being shallower and simpler, adapt more easily to increased androgen levels.
Another factor is the variation in 5α-reductase isoforms, enzymes that convert testosterone to DHT. These isoforms are distributed differently across the body, contributing to the contrasting effects of androgens on scalp versus body hair.
Other Hormones That Affect Hair Health
While androgens are often the focus of hair loss discussions, other hormones also significantly influence follicle health and hair growth.
- Insulin and insulin-like growth factor-1 (IGF-1): These hormones amplify the damaging effects of androgens. Women with insulin resistance often notice faster hair loss progression compared to those with normal insulin sensitivity.
- Estrogen: This hormone acts as a natural defense against androgen-related hair loss. It prolongs the growth phase of hair cycles, helping follicles stay active and produce thicker strands. Estrogen also reduces 5α-reductase activity, limiting local DHT production in the scalp. When estrogen levels drop - due to PCOS, menopause, or other hormonal imbalances - this protective effect diminishes, allowing androgens to cause more damage.
- Thyroid hormones: These regulate the speed of hair growth cycles. Low thyroid function slows cell division in follicles, leading to thin, brittle hair. Overactive thyroid, on the other hand, speeds up hair cycles to the point where follicles become exhausted and enter resting phases prematurely.
- Cortisol: Known as the stress hormone, cortisol disrupts hair growth by diverting energy away from non-essential functions like hair production. Chronic stress keeps cortisol levels high, pushing follicles into resting phases and delaying new growth. Elevated cortisol also worsens insulin resistance, creating a cycle that increases androgen sensitivity.
The interaction between these hormones highlights the complexity of hair loss. For women with conditions like PCOS, elevated androgens, insulin resistance, and reduced estrogen levels often combine to accelerate hair loss.
Addressing hair loss effectively requires a holistic approach that tackles multiple hormonal pathways rather than focusing on androgens alone. Oana Health offers tailored treatment plans that address underlying imbalances, including insulin sensitivity, androgen levels, and other hormonal factors, to support healthier hair growth.

Hormonal Conditions That Cause Hair Loss
Hormonal imbalances can interfere with sebum production and follicle health, often leading to hair thinning and loss.
PCOS and High Androgen Levels
Polycystic Ovary Syndrome (PCOS), a condition affecting many women of reproductive age, is marked by elevated androgen levels. These hormones can increase sebum production and shrink hair follicles, which contributes to thinning hair. In women with PCOS, the hair loss often follows a pattern, particularly affecting the crown where follicles are more sensitive to androgens. At the same time, many women with PCOS experience hirsutism - excessive body and facial hair - while struggling with thinning hair on the scalp. This hormonal imbalance is frequently linked to metabolic issues, such as insulin resistance, further complicating the condition.
Insulin Resistance and Hair Loss
Insulin resistance, much like excess androgens, can upset the delicate hormonal balance needed for healthy hair. When the body produces extra insulin to combat resistance, it can stimulate the ovaries to produce more androgens, worsening the imbalance. Elevated insulin levels also increase IGF-1 (Insulin-like Growth Factor 1), which can make hair follicles more sensitive and lead to increased sebum production. This combination often results in clogged follicles, inflammation, and impaired follicle function - all factors that contribute to hair thinning.
Androgenic Alopecia in Women
Female pattern hair loss, also known as androgenic alopecia, is one of the most common types of hair loss in women. It typically causes gradual thinning at the crown while sparing the frontal hairline. The Ludwig Scale is often used to classify the progression of this condition, ranging from mild thinning to more severe hair loss. Hormonal changes, such as those during pregnancy, postpartum, or menopause, can trigger or worsen this type of hair loss. Additionally, excess sebum production in affected individuals may lead to a greasy scalp, further complicating follicle health and hair growth.
Addressing these hormonal imbalances requires targeted solutions. Oana Health offers personalized, science-based treatment plans designed to manage conditions like PCOS and insulin resistance, supporting healthier hair growth and better scalp health.

FAQs
How do hormonal changes during menopause impact hair loss and scalp oil production?
During menopause, declining estrogen levels often result in reduced sebum production. This can leave the scalp and hair feeling drier, more fragile, and more likely to break. On the flip side, a rise in androgen activity may contribute to androgenic alopecia (a form of hair thinning) and alterations in sebaceous glands, which can sometimes lead to oily skin in specific areas.
These hormonal changes play a significant role in both hair loss and shifts in scalp oil production during this phase of life.
How does insulin resistance contribute to hormonal hair loss and oily scalp?
Insulin resistance is often linked to increased levels of androgens, especially DHT (dihydrotestosterone). Elevated DHT can cause hair follicles to shrink, leading to hair thinning and eventual hair loss. On top of that, it stimulates the sebaceous glands, which ramps up oil production on the scalp. Together, these effects create a vicious cycle that exacerbates both hair loss and excessive scalp oiliness.
Taking steps to manage insulin resistance - whether through lifestyle adjustments or medical treatments - can help regulate hormones, reduce scalp oiliness, and promote healthier hair growth.
Can sensitivity to androgens that affects hair and skin be managed with treatment?
Sensitivity to androgens can play a role in issues like hair loss and excess oil production. While you can’t change a genetic predisposition to androgen sensitivity, there are effective ways to manage the symptoms.
For hair loss, finasteride and minoxidil are two FDA-approved treatments often recommended. Women might also find spironolactone, an antiandrogen, beneficial for reducing androgen-related effects on both hair and skin. These options are typically tailored to suit individual medical histories and specific needs.
If you’re noticing symptoms linked to androgen sensitivity, it’s a good idea to consult a healthcare provider who specializes in hormonal health. They can help you identify personalized treatment strategies to address your concerns.
