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. This will take a while because you must grow out new hair. Treat your hair gently; use as few hair products as you can. My hair is baby fine, but is now below my waist. I loosely braid it before going to bed, but do not tie the ends, and brush, brush, but with a soft natural brush. Long hair such as we both seem to have is expensive in terms of good brushes, but they last forever. Good luck.

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.

Bulk MSM from feed store long as it is pure. Inexpensive. Cannot hurt you only help. I use a tespoon a day in black coffee that is just barely warm. Nails turn to iron and hair is lots stronger. Good for lots of things. Google.

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
