Hair loss can be a troubling symptom for anyone, but if you have diabetes or insulin resistance, it may be especially concerning. Understanding the connection between these conditions can help you get to the root of the problem and take steps to regrow your hair.
How Diabetes and Insulin Resistance Cause Hair Loss
If you have diabetes, your body either does not produce enough insulin or does not use insulin effectively. High insulin levels contribute to hair loss in a few key ways:
- Women with insulin resistance or PCOS often have elevated testosterone induced by high insulin. This male hormone can lead to hair thinning and loss.
- Testosterone gets converted into dihydrotestosterone (DHT), which causes pattern baldness in both men and women. Insulin resistance leads to increased DHT.
- Excess sugar from uncontrolled diabetes can damage blood vessels throughout the body. Damaged vessels may not deliver enough oxygen and nutrients to hair follicles, disrupting the hair growth cycle.
In addition, people with type 1 diabetes are prone to an autoimmune form of hair loss called alopecia areata. This causes complete but patchy hair loss.
Diabetes can also trigger thyroid disorders, which are another cause of excessive hair shedding. Certain diabetes medications have hair loss as a side effect as well.
Getting to the Root of Hair Loss
If your hair loss results from uncontrolled blood sugar, the most effective solution is to closely monitor your levels and take medication as directed. Counseling and stress-reduction techniques can help too, since mental health influences diabetes management.
Eating a balanced, low-glycemic diet and exercising regularly will also bring blood sugar under control and deliver nutrients to hair follicles. Take a complete multivitamin to replace any vitamin and mineral deficiencies.
Biotin, zinc, iron and vitamin D supplements support healthy hair. Do not exceed the recommended daily intake for biotin, as very high levels affect thyroid tests.
See your doctor about medications like minoxidil (Rogaine), finasteride or spironolactone if natural remedies are insufficient. These can stimulate regrowth in pattern baldness.
Biotin, Zinc, Iron and Vitamin D Supplements Support Healthy Hair
Certain vitamins and minerals are especially important for healthy hair growth. Taking supplements to increase your levels may help reduce hair loss.
Biotin is a B vitamin that aids keratin production in hair. Many shampoos and hair products contain biotin, but oral supplements can also be useful. Adults should aim for 300-500 mcg of biotin per day for hair loss. Exceeding 10,000 mcg starts to interfere with thyroid tests, so do not mega-dose this vitamin.
Zinc is essential for protein synthesis and cell division which allow hair to regenerate. The recommended daily zinc intake is 8-11 mg for adult women and 11 mg for adult men. Look for a supplement with zinc gluconate or zinc sulfate.
Iron carries oxygen in the blood to hair follicles. Low ferritin (stored iron) levels can trigger hair shedding. Have an iron panel done at your next physical. If deficient, an iron supplement taken with vitamin C will improve absorption.
Vitamin D promotes healthy cell growth and regeneration. Blood levels below 30 ng/ml may contribute to hair loss. Get your vitamin D tested and supplement accordingly with 600-800 IU per day, ideally as vitamin D3. This may also boost the effectiveness of minoxidil treatment.
A balanced multivitamin will provide proper doses of each of these hair-healthy nutrients. Look for options marketed for hair, skin and nails that contain extras like vitamin C, folic acid and silica. Take care not to overdo certain vitamins like biotin and vitamin A. A comprehensive supplement along with targeted diabetes treatment offers the best chance of restoring your hair.
Exercise Improves Circulation
Regular exercise improves circulation to nourish hair follicles. Proper blood flow delivers oxygen and prevents loss from developing on the scalp, face and body. Check with your doctor before starting any new fitness routine.
Have Patience with Treatment
It takes time to get diabetes under control and reverse related hair loss. With consistent blood sugar monitoring, a healthy lifestyle and targeted medications, you should see gradual improvement. Focus on overall health, and your hair should start to recover in a few months.
If you’ve experienced complete bald patches, see a dermatologist. This points to an autoimmune disorder that requires specialized treatment.
Stay Positive!
Hair loss can shake your confidence, but rest assured many options exist to restore your tresses. Getting diabetes under control is the first step to reviving healthy hair growth.
