Is DHT Behind Your Hair Loss? Here’s What Every Woman Should Know

Hair thinning is rarely caused by just one thing. For many women, it’s the result of several factors working together, including age, hormonal changes, stress, genetics, inflammation, nutrition. But one potential contributor many people don’t know much about is dihydrotestosterone (DHT), a hormone that can gradually shrink hair follicles in people who are genetically sensitive to it.

Understanding DHT is important because not all hair loss is the same. The more you understand why your hair is changing, the better equipped you’ll be to support healthy follicles and choose the approach that’s right for you.

What Is DHT?

DHT (dihydrotestosterone) is a hormone your body naturally produces from testosterone. Both men and women make testosterone, and both produce DHT. In men, DHT is central to the development of the male sex organs, and in women it helps keep androgens (a group of hormones including testosterone) balanced.[1] Too much DHT in women can trigger hair loss, acne and excess body hair.[2] For both women and men, if they’re prone to being more sensitive to DHT, it can bind to the follicles and lead to hair thinning.[3]

Think of it like sunlight. Two people can spend the same amount of time in the sun, but one barely tans while the other burns within minutes. The difference is how each person’s skin responds to it. Hair follicles work in much the same way. Two people can have similar DHT levels, but one may experience hair thinning while the other never does because their follicles respond differently.

For women, certain conditions including PMOS (polyendocrine metabolic ovarian syndrome, which used to be known as PCOS), or naturally higher androgen levels can add another layer by increasing the amount of DHT circulating in the body and amplify the impact of DHT on hair follicles that may already be genetically sensitive.[4]

How Exactly Does DHT Affect Hair?

Each hair follicle is like a tiny factory that repeatedly grows, rests, sheds, and regrows a strand of hair. Under normal conditions, this cycle follows a regular pattern and keeps producing hair.[5]

But when a follicle is sensitive to DHT, the hormone gradually changes how that factory operates. Over time, DHT signals the follicle to become smaller, a process known as miniaturization. As the follicle shrinks, each new hair it produces becomes a little finer, shorter, and less pigmented than the one before it. Eventually, some follicles become so small that they stop producing visible hairs altogether.[6]

This is why DHT-related hair loss rarely happens overnight. It’s often a slow, progressive process that unfolds over months or even years. For women this can look like a widening part, thinning at the crow, a receding hairline around the temples and hair that feels finer overall. Men often notice recession at the temples or thinning on the crown.[7] Because the changes are gradual, many people don’t recognize them until they’ve been happening for quite some time.

Sign	Where It Shows Up	Who Notices It Most
Widening part	Top of the scalp	Women
Thinning at the crown	Crown of the head	Women and men
Receding hairline	Temples	Women and men
Finer-feeling hair overall	Throughout the scalp	Women
Recession at temples or crown thinning	Temples and crown	Men

Who Is Most Likely to Experience DHT-Related Hair Loss?

Genetics is one of the biggest factors, but hormonal changes can also influence how your follicles respond to DHT.[8] Women with PMOS, people with naturally higher androgen levels, and women experiencing the hormonal shifts of perimenopause and menopause may be more likely to experience DHT-related changes in their hair.[9] Also important to note: Having high DHT doesn’t automatically mean you’ll lose your hair, just as having normal DHT doesn’t guarantee you won’t. Hair loss is usually the result of several factors working together, including genetics, hormone levels, age, and how sensitive your hair follicles are to DHT.[10]

What You Can Do

If you’re experiencing hair thinning, talk to your doctor. Hair loss is usually diagnosed based on the pattern of thinning, your medical history, physical exam, and sometimes dermoscopy (a close examination of the scalp with a special magnifying device).[11] [12] In many cases, the issue isn’t how much DHT your body makes, it’s that your hair follicles are genetically more sensitive to it. If your doctor suspects an underlying hormonal imbalance, such as PMOS or elevated androgen levels, they may order hormone testing along with other blood work to help identify potential contributors. A dermatologist can also evaluate the pattern of your hair loss and recommend additional testing if needed.

Taking a comprehensive approach to support strong hair can help, including making sure you’re getting nutrients key to your hair including protein, iron, B vitamins and zinc, caring for your scalp, and managing stress (which can cause elevated cortisol levels that can impact the hair growth cycle).[13]

Certain botanicals have also been studied for their ability to support healthy hormone pathways involved in DHT metabolism. Ingredients including pygeum bark extract, nettle root extract, and fenugreek extract are increasingly being incorporated into targeted hair wellness formulas because of their potential to support DHT-sensitive follicles.[14][15]

What You Can Do	Why It Helps	Examples or Focus Areas
Talk to your doctor	Helps identify whether DHT sensitivity or another factor is driving your hair changes	Medical history, physical exam, dermoscopy
Ask about hormone testing	Can reveal underlying imbalances like PMOS or elevated androgens	Hormone panels, blood work
Prioritize key nutrients	Supports the biological processes hair follicles need to function well	Protein, iron, B vitamins, zinc
Care for your scalp and manage stress	Elevated cortisol can disrupt the hair growth cycle	Scalp care routine, stress management practices
Consider DHT-supportive botanicals	May support healthy hormone pathways involved in DHT metabolism	Pygeum bark extract, nettle root extract, fenugreek extract

The Takeaway

DHT is a normal hormone, but in people whose hair follicles are sensitive to it, it can gradually shorten the hair growth cycle and shrink follicles over time. Because these changes happen slowly, they’re often mistaken for normal aging.

If you’re noticing a widening part, thinning around your crown, or a receding hairline, it’s worth talking with a dermatologist or healthcare provider to determine the underlying cause. The sooner you identify what’s driving your hair changes, the sooner you can develop a plan that supports healthier hair from the inside out.

Frequently Asked Questions

Can women have DHT-related hair loss?

Yes. Although DHT is often associated with male pattern baldness, women produce DHT too. In women who are genetically sensitive to DHT or who have hormonal conditions such as PCOS (now referred to as PMOS) or higher androgen levels, DHT can contribute to gradual hair thinning. Women typically notice a widening part, thinning at the crown, or an overall decrease in hair density rather than a dramatically receding hairline.

Can my doctor test my DHT levels?

Yes, but a blood test for DHT isn’t routinely used to diagnose hair loss. Many people with DHT-related hair thinning have normal DHT levels. In many cases, the issue isn’t how much DHT your body makes, it’s that your hair follicles are genetically more sensitive to it. If your doctor suspects an underlying hormonal imbalance, they may recommend hormone testing along with other blood work to help identify potential contributors to your hair loss.

If hair loss runs in my family, am I destined to lose my hair?

Not necessarily. A family history of hair thinning can increase your risk because sensitivity to DHT is largely influenced by genetics. But genetics are only one piece of the puzzle. Hormones, nutrition, stress, overall health, and how you care for your hair can all influence how your hair changes over time. While you can’t change your genes, recognizing the early signs of thinning and supporting your hair follicles with healthy habits can help you maintain stronger, resilient hair for longer.
