How Can I Grow New Longer, Stronger Hair?

I don't know about making your hair "thicker" but I can tell you that taking Biotin will help you grow more hair. It also strengthens finger nails. Biotin is a vitamin you can buy almost anywhere that sells vitamins.

You may be also blessed/cursed with fine textured hair. Avoid harsh shampoos; I used DHC's (a Japanese mail order brand, look up DHC on 'net), Use only a very soft brush, no dyes or hair dryers. After washing your hair, allow it to nearly dry before brushing, do not comb until all the tangles are out. Follow a healthy diet.

Yes, biotin can help...or you can buy a supplement formulated for "hair, nails, and skin". Any drugstore or Walmart should carry it. I have a question for you though. Have you always had frail hair? If not, it could be an indication of a health problem such as hypothyroidism. If so, you may also notice weight gain/difficulty losing weight, depression, skin problems, and/or feel cold all the time.

Bulk MSM from feed store long as it is pure. Inexpensive. Cannot hurt you only help.

You grow long luscious hair through using products that won't extract your hairs emollients and take n eat something with much Vitamin k, Keratin is the key
