DHT (dihydrotestosterone) is a hormone that plays a key role in hair loss, especially in conditions like male and female pattern baldness. Here's the quick breakdown:
- What is DHT? It's a hormone derived from testosterone via the enzyme 5-alpha-reductase. It's stronger than testosterone and impacts hair follicles, oil production, and other bodily functions.
- How does it cause hair loss? DHT binds to androgen receptors in hair follicles, causing them to shrink (miniaturization). This leads to thinner hair and, over time, stops hair growth altogether.
- Who is affected? Both men and women can experience DHT-related hair loss, but the patterns differ:
- Men: Receding hairlines, thinning at the crown, and eventual bald spots.
- Women: Diffuse thinning across the scalp, often worsened by hormonal changes like menopause or PCOS.
Key Steps to Manage DHT Hair Loss:
- Preventive Care: Use gentle shampoos, avoid heat styling, and manage stress.
- DHT-Blocking Products: Shampoos with ketoconazole, saw palmetto, or caffeine can help reduce DHT's effects.
- Prescription Treatments: Options like oral minoxidil or topical spironolactone offer stronger solutions for hair regrowth and follicle protection.
- Telehealth Support: Platforms like Oana Health provide easy access to personalized treatments and ongoing care.
Takeaway: Early action is crucial to slow hair loss and protect existing hair. Treatments often take 3–6 months to show results, so consistency and professional guidance are key.

How DHT Causes Hair Loss
Hair loss caused by DHT doesn't happen overnight. It’s a gradual process that unfolds over months or even years, as cellular changes slowly take effect.
How DHT Affects Hair Follicles
DHT binds to androgen receptors in hair follicles, triggering changes that disrupt the hair growth cycle. The biggest impact occurs during the anagen phase, which is when hair actively grows. Normally, this phase can last anywhere from two to seven years, allowing hair to grow thick and long.
When DHT interferes, it shortens the anagen phase while lengthening the telogen phase, or the resting stage. This leaves hair follicles dormant for longer periods, reducing the production of new hair.
Another key effect of DHT is follicular miniaturization. Over time, the hair follicles shrink with each growth cycle, producing thinner, shorter strands. Eventually, the follicles may become so small that they can only produce vellus hair - the soft, nearly invisible hair that naturally covers much of your body.
This doesn’t mean your hair is falling out faster. Instead, it’s becoming finer and shorter, making your scalp more noticeable, especially under bright light.
The enzyme 5-alpha-reductase, particularly its Type II variant found in hair follicles, plays a major role here. It converts testosterone into DHT right at the follicle level. Hair follicles in areas prone to male pattern baldness have higher concentrations of this enzyme, making them particularly vulnerable to DHT's effects.
These cellular changes explain the distinct hair loss patterns seen in both men and women.
Hair Loss Patterns in Men vs. Women
DHT-related hair loss manifests differently in men and women, influenced by hormone levels, receptor sensitivity, and genetics.
Male pattern baldness often follows a predictable path. It typically starts with a receding hairline at the temples, forming the classic "M" shape. Thinning may also begin at the crown, creating a circular bald spot. Over time, these areas expand and may eventually connect, leaving hair only on the sides and back of the head. This pattern occurs because these follicles have a higher density of androgen receptors and 5-alpha-reductase.
Men generally have higher testosterone levels, which means more DHT is produced. Their hair follicles are also more sensitive to DHT's effects. While some men notice rapid hair loss within a few years, others may experience a slower progression over decades.
Female pattern hair loss, on the other hand, looks different. Instead of distinct bald spots, women typically experience diffuse thinning across the scalp, with the most visible changes at the crown and along the part line. The hairline usually stays intact, though slight recession at the temples can occur.
Women benefit from the protective effects of estrogen, which helps counteract some of DHT's impact on hair follicles. However, during menopause, when estrogen levels drop significantly, many women notice an acceleration in hair thinning. Women with PCOS may also experience increased hair loss due to higher androgen levels, which boost DHT production.
The timing of hair loss varies between genders. Men may start noticing changes in their twenties or thirties, while women often don’t see significant thinning until their forties, fifties, or after menopause. That said, hormonal shifts during pregnancy, postpartum, or from certain medications can trigger earlier hair loss in women who are genetically predisposed.
The severity and progression of hair loss in both men and women depend heavily on genetic factors. You might inherit sensitivity to DHT from either parent, and the combination of genes from both sides can determine when hair loss begins, how quickly it progresses, and which areas of the scalp are most affected.
How to Manage DHT-Related Hair Loss
Understanding how DHT contributes to hair follicle miniaturization highlights the importance of acting early. Managing DHT-related hair loss requires a mix of preventive care and targeted treatments to protect existing hair before significant thinning sets in.
Preventive Hair Care Practices
Taking care of your hair gently is the first step in any strategy to combat DHT-related hair loss. Since DHT-affected follicles are already under stress, avoiding further damage is crucial. Opt for sulfate-free shampoos, which help maintain your scalp's natural oils, and limit hair washing to every other day or about three times a week. Washing too often can irritate sensitive follicles and worsen inflammation.
Be cautious with heat styling - keep tools below 300°F and always use a thermal protectant. Avoid chemical treatments like bleaching, perming, or relaxing, as they can weaken the hair structure and cause irreversible damage to already vulnerable follicles.
Incorporating a scalp massage into your daily routine could be beneficial. Massaging your scalp for five minutes with diluted rosemary or peppermint oil may improve blood flow to the follicles, potentially helping to counteract some of DHT's harmful effects.
Managing stress is another critical, yet often overlooked, aspect of hair health. Chronic stress can raise cortisol levels, which not only accelerates hair loss but also amplifies DHT's impact. Regular exercise, 7–9 hours of sleep per night, and stress-reduction techniques like meditation or yoga can help maintain hormonal balance.
For those with a family history of hair loss, starting preventive measures in your twenties or early thirties can make a big difference. Alongside daily care, using targeted products can further reduce DHT's impact.
DHT-Blocking Shampoos and Conditioners
Shampoos containing ingredients like 2% ketoconazole, saw palmetto, or caffeine can help minimize DHT's effects. Ketoconazole is known for its anti-androgenic properties, which can lower DHT levels in the scalp. Meanwhile, caffeine-infused shampoos may stimulate hair follicles, especially when left on the scalp for at least two minutes.
However, DHT-blocking shampoos have a key limitation: their short contact time with the scalp. For this reason, they’re most effective when used as part of a broader treatment plan rather than as standalone solutions.
To see results, use these shampoos 3–4 times a week for at least 3–6 months. Let the product sit on your scalp for 3–5 minutes before rinsing to maximize its benefits.
Prescription Treatments for Hair Loss
If over-the-counter options aren’t enough, prescription treatments can provide more powerful solutions. Medications like oral minoxidil and topical spironolactone, prescribed under medical supervision, are effective at increasing hair density and prolonging the growth phase.
Oral minoxidil is gaining attention as an effective option, especially for women dealing with diffuse thinning. Low doses (ranging from 0.25mg to 2.5mg daily) can significantly improve hair density with minimal side effects, offering systemic benefits in a convenient, once-daily form.
Topical spironolactone is another option, delivering targeted DHT-blocking effects without impacting the entire body. This treatment is particularly useful for women with PCOS or hormonal hair loss, as it works by blocking androgen receptors directly in the hair follicles.
One of the biggest advantages of prescription treatments is that they can be tailored to your specific needs. A healthcare provider can adjust doses and combinations based on your hormone levels, hair loss pattern, and how well you’re responding to treatment.
Telehealth services make it easier than ever to access these treatments. Platforms like Oana Health offer remote consultations and deliver prescriptions straight to your door. They provide options like oral minoxidil and topical spironolactone, both of which are backed by scientific research.
Consistency is key with these treatments. It typically takes 3–6 months to notice visible results, with optimal outcomes often appearing after 12–18 months. Starting early is essential, as these medications are more effective at preserving existing hair than regrowing hair from follicles that have become completely dormant.
