7 Expert-Approved Vitamins for Hair Growth That Actually Work
- Saw Palmetto: Known for blocking dihydrotestosterone, a significant player in hair loss. Consult with your healthcare professional, as it’s deemed effective.
- Ashwagandha: An antioxidant that helps with stress, supports hair growth, and reduces breakage.
-
Tocotrienol: Helps increase hair density.
-
Curcumin: Reduces dihydrotestosterone linked to hair loss.
-
Collagen: While its effectiveness is still under debate, anecdotal evidence and research suggest collagen supplements may enhance hair growth, strength, and benefit skin and nails.
-
Biotin: Formerly a popular hair growth vitamin, now less favored due to limited data. Generally safe, but high doses may cause acne or affect lab results.
Who should take these supplements & the best way to consume:
If factors like daily caffeine intake, medication use, stress, or certain lifestyle habits deplete your micronutrient levels, supplements can help replenish them. Most people can take these supplements, with specific formulations tailored to different demographics. Avoid certain ingredients if pregnant or trying to conceive.
Which vitamin deficiency may cause hair loss:
Vitamin D and B deficiencies are commonly seen in hair loss cases. While not always the direct cause, they are crucial for hair growth. Other important tests include checking blood counts for anemia and thyroid function.
Are there any side effects to be aware of:
There can be potential side effects, especially when using botanicals. Use reputable sources due to limited research. While rare, some botanicals targeting dihydrotestosterone may lead to low testosterone side effects. Excessive biotin intake may cause acne and interfere with blood tests. Iron supplements can cause constipation, and collagen may lead to diarrhea or gastrointestinal upset in some individuals.
