HRT and Your Hair
Hormone Replacement Therapy (HRT) can be life-changing for managing menopause symptoms, but many people are surprised to see its effects on their hair and scalp. Let’s dive into the science behind hormones, how HRT works, and what I’ve observed in my clinic about the changes it can bring to your hair health. I’ll also share tips on nutrition, product recommendations, and treatments that can help.
Hormones are your body’s internal messengers, coordinating everything from mood to metabolism to hair growth. The process begins with the hypothalamus in your brain, which sends signals to the pituitary gland, known as the “master gland.” The pituitary then secretes hormones that stimulate other glands, such as the ovaries, adrenal glands, and thyroid, to produce hormones like estrogen, progesterone, testosterone, and cortisol.
Hair health is particularly sensitive to the balance of these hormones:
-
Estrogen: Promotes hair growth and supports the anagen (growth) phase of the hair cycle.
-
Progesterone: Acts as a mild anti-androgen, helping to counteract the effects of testosterone.
-
Testosterone and DHT: In higher levels, these can shrink hair follicles, leading to thinning or hair loss.
When menopause causes hormone levels to fluctuate or decline, this balance is disrupted, which often leads to thinning hair or changes in scalp health.
HRT is designed to replenish declining hormone levels, typically using a combination of estrogen and, in some cases, progesterone or testosterone.
-
Estrogen in HRT: Can improve hair density and support scalp health by keeping the growth phase longer.
-
Progesterone in HRT: Helps counteract the effects of testosterone-derived DHT.
-
Testosterone in HRT: Sometimes added for energy and libido but may lead to increased hair shedding if not carefully balanced.
The key is balance—replacing hormones in a way that mimics the body’s natural rhythms to minimize side effects.
Over the years, I’ve worked with many clients navigating HRT and its impact on their hair. Here are some common patterns I’ve noticed:
-
Initial Shedding: Some clients experience increased shedding when they first start HRT, likely due to the body adjusting to hormonal changes. This often stabilizes after a few months.
-
Improved Density: For others, HRT has been a game-changer, restoring volume and density to thinning hair.
-
Scalp Sensitivity: Hormonal shifts can make the scalp more prone to irritation, oiliness, or dryness, especially if testosterone levels are included in treatment.
-
Androgenic Effects: In some cases, an imbalance in testosterone or DHT can lead to hair thinning along the temples or crown.
-
Itchy Scalp and Sores: In clinic a client experienced an itchy scalp that progressed to sores after starting HRT. We incorporated low-level light therapy (LLLT), and it significantly improved both the scalp condition and overall hair health as new hair emerged.
1. Be Patient with Adjustments
It can take several months for your body to adjust to HRT. During this time, you may notice changes in your hair, but these often stabilize as your hormone levels balance out.
2. Support Your Hair from the Inside Out
-
Diet: Focus on foods that help balance hormones naturally:
-
Phytoestrogens: Found in flaxseeds, soy, and chickpeas, these plant-based compounds mimic estrogen in the body.
-
Healthy Fats: Avocados, nuts, and olive oil support hormone production and scalp health.
-
Protein: Lean meats, eggs, and lentils are essential for building strong, healthy hair.
-
Antioxidants: Blueberries, spinach, and sweet potatoes fight oxidative stress that can damage hair follicles.
-
-
Supplements: Consider adding collagen, omega-3s, or a targeted hair supplement, especially if you’re experiencing excessive shedding.
3. Choose the Right Products
-
Use gentle, sulfate-free shampoos and nourishing treatments that support the scalp barrier.
-
Ingredients like red clover, caffeine, and rosemary (like those in my Revitalise Serum) can encourage healthy growth.
-
For those with sensitive or irritated scalps, I recommend trying products like Nourished By Oil, Revitalise Serum or Reinforcement treatment, to calm and soothe while igniting healthy hair growth.
4. Try Low-Level Light Therapy (LLLT)
LLLT can stimulate hair follicles, increase blood flow to the scalp, and help soothe irritation or inflammation. It’s an excellent option for those experiencing hair thinning or scalp sensitivity.
5. Work with Your Doctor
If you’re noticing significant hair loss or thinning, ask your doctor about the balance of your HRT prescription. Testing DHT levels or adjusting dosages can make a big difference.
HRT is a powerful tool for managing hormonal shifts, and with the right support, it can have a positive impact on your hair and scalp health. If you’re navigating these changes, remember that you’re not alone, and there are solutions to help you feel confident again.
