DHT and hair loss are closely linked, especially in cases of androgenic alopecia—commonly known as female pattern baldness. This condition occurs when testosterone is converted into DHT (dihydrotestosterone), a hormone that can shrink hair follicles and lead to gradual thinning. Typically, it begins with hair loss in an “M” pattern at the front of the scalp, and it affects over 30 million women in the U.S. alone. Fortunately, several treatments are available to help manage and reduce the effects of DHT on hair. In the sections ahead, explore these treatment options along with their potential side effects. Keep reading to learn more.
What Is DHT And How Does It Affect Hair?
DHT, or dihydrotestosterone, is a more potent derivative of testosterone. Although it’s crucial for certain body functions, its overproduction can negatively impact hair health—especially in women. Elevated DHT levels are known to trigger female pattern baldness, leading to gradual hair thinning rather than complete baldness.
In fact, a recent survey among 32,601 U.S. adults revealed that 46% of women fear hair loss, with those aged 18 to 24 expressing the greatest concern (57%). This highlights how emotionally and socially significant the issue can be.
Here’s how the process works: Testosterone gets converted into DHT by the enzyme 5-alpha reductase (5-AR). When DHT binds to hair follicle receptors, it causes them to shrink. As a result, the hair’s natural growth cycle shortens, leading to thinning hair and delayed regrowth. In women, excessive DHT may also lead to facial hair growth and other masculine traits.
Let’s now explore the available treatments that can help manage the effects of DHT on your hair.
DHT And Hair Loss: Treatment Options
There are generally two approaches to address hair loss caused by DHT:
- Blockers – Prevent DHT from binding to receptors in the hair follicles.
- Inhibitors – Stop the conversion of testosterone into DHT.
Although most of these options are non-surgical, it’s essential to consult a dermatologist before starting any medication.
1. Minoxidil
Minoxidil is an FDA-approved topical solution that encourages hair growth by prolonging the anagen (growth) phase. According to studies, about 44% of women using 2% minoxidil experienced visible hair regrowth.
2. Spironolactone
This drug is commonly prescribed to women dealing with androgenetic alopecia or hirsutism. It works by blocking androgen receptors and reducing androgen production. A typical dose is 200 mg/day, which has shown promising results in reducing hair thinning.
3. Cyproterone Acetate
Used to treat hyperandrogenism, this medication inhibits gonadotropin-releasing hormone and blocks androgen receptors. It is particularly helpful for women struggling with hormonal imbalance.
4. Flutamide
Flutamide is a newer treatment option that works by blocking androgen receptors. In studies, women taking 250 mg/day for one year experienced greater hair density improvements than those taking cyproterone acetate or finasteride.
5. Finasteride
Finasteride is a 5-alpha reductase inhibitor that blocks testosterone from converting into DHT. While effective, it’s not suitable for women of childbearing age due to potential birth defect risks in male fetuses.
Expert Insight:
David Carvalhao, an entrepreneur, shared his experience with DHT and hair loss. He used both Finasteride and Minoxidil to treat early-onset male pattern baldness and noticed new hair growth after six weeks of combining the two, along with vitamins.
Possible Side Effects Of DHT Blockers
Although these treatments can be effective, they may also come with certain side effects:
- Minoxidil may cause scalp irritation due to propylene glycol.
- Spironolactone could lead to menstrual irregularities, fatigue, and electrolyte imbalances.
- Finasteride poses a risk of birth defects and should not be used by women who may become pregnant.
Your healthcare provider will assess whether medical or cosmetic treatment is more appropriate based on your condition.
Cosmetic Procedures For DHT-Related Hair Loss
If medications are not suitable or effective, cosmetic procedures may provide additional support in managing DHT and hair loss.
Platelet-Rich Plasma (PRP) Therapy
PRP therapy is a regenerative treatment that involves injecting platelet-rich plasma from your own blood into thinning areas of the scalp. Studies show this method significantly improves hair density without causing adverse reactions. It’s a promising non-invasive option that’s growing in popularity among both men and women.
Laser Therapy for DHT and Hair Loss
Laser treatment is another effective, non-invasive option to combat DHT and hair loss. It works by irradiating low-level laser photons into the scalp tissue. These photons are absorbed by the hair follicles, which helps improve blood circulation and stimulate follicular activity.
As blood flow improves, so does nutrient delivery to the hair follicles. This results in stronger, healthier strands and encourages regrowth in thinning areas. You can opt for professional sessions at a clinic or invest in an FDA-approved laser cap for home use. While in-office sessions may cost anywhere between $200 to $500 per treatment, a good-quality laser cap could cost $600 to $1200 depending on the brand.
Hair Transplantation for Advanced Hair Loss
For more severe cases of hair loss due to DHT, hair transplantation may be an option. This surgical procedure involves removing hair follicles from one part of the scalp (usually the back or sides) and transplanting them to areas affected by baldness.
While this technique can yield permanent and natural-looking results, it’s important to note:
- It may leave minor scarring
- Recovery time is required
- It’s significantly more expensive than other treatments
On average, a hair transplant can cost $4,000 to $15,000, depending on the extent of the procedure and the clinic’s location.
Foods That Naturally Block DHT
Aside from medical and cosmetic treatments, dietary choices can also play a big role in managing DHT and hair loss. Certain foods contain nutrients and compounds that help block DHT production or reduce its effects on the hair follicles.
Here are some DHT-blocking foods you can include in your diet:
Biotin-Rich Foods
- Egg yolks
- Whole grains
- Nuts
Biotin helps strengthen hair strands and support scalp health.
Lysin-Rich Foods
- Coffee
- Green tea
- Black tea
- Boiled eggs
- Pumpkin seeds
- Flaxseeds
- Peanuts
Lysine supports collagen production and helps manage testosterone levels.
Lycopene-Rich Foods
- Tomatoes
- Watermelon
- Bananas
- Mangoes
- Beets
- Grapefruit
Lycopene is known for its antioxidant properties, which help neutralize excess DHT.
Zinc-Rich Foods
- Spinach
- Kale
- White mushrooms
Zinc helps regulate hormone levels and supports hair tissue growth and repair.
Protein-Rich Foods
- Soy
- Soybeans
- Edamame
- Tempeh
- Fatty fish
- Legumes
Proteins are essential for keratin production, which is the building block of hair.
Quercetin-Rich Foods
- Apples
- Berries
- Asparagus
- Kale
- Spinach
Quercetin is a flavonoid that reduces inflammation and inhibits DHT production.
Understanding the Difference: DHT vs. Testosterone
Though DHT is derived from testosterone, their roles and effects on the body differ. Testosterone supports muscle mass, libido, and overall vitality, whereas DHT has a more targeted impact—especially on hair follicles and skin.
High levels of DHT in women can lead to unwanted symptoms like facial hair growth and hair thinning, which is why balancing these hormones is crucial for both appearance and overall well-being.
Managing DHT and Hair Loss: Final Thoughts
Hair loss can feel frustrating and overwhelming, especially when it’s hormone-related. However, now you know there are multiple approaches to managing DHT and hair loss:
- Medications like minoxidil and spironolactone
- Cosmetic solutions like laser therapy or hair transplantation
- Natural remedies and dietary adjustments
- Practicing a healthy lifestyle with balanced nutrition, stress management, and regular exercise
With patience and the right treatment plan—tailored to your body and needs—you can regain hair health and confidence far sooner than expected.
