I have fairly fine, medium hair that tends to be thin at the ends. I just recently started taking L-cystine everyday, and I've noticed new growth sticking out of my head. Anyone else try this?

Oh yes indeedy!!!! I have a rinse out treatment with this in it and I've found that I have loads of new spikey growth - anyone with fine hair should give it a go - that and biotin shampoo and scalp rub!!!

Hi Girls,
I'm very happy this works for you both!
I just ordered hair vitamins and it has this ingredient in them.  Where did you get the topical form?  I've never seen it.  thanks.  btw, what is it?  

Here is what an herbal site says about it:

L Cysteine is a non-essential amino acid that is an important component of hair, nails and the keratin of the skin.
L Cysteine stabilizes protein structure and aids in the formation of collagen, thereby promoting healthy skin, hair and nail texture.
It is used in the treatment of respiratory disorders such as chronic bronchitis.
It stimulates white blood cell activity in the immune system to help build resistance to disease.
Faster recovery from surgical operations and burns is another benefit.

I did use this for about a year and I didn't notice any difference going on it or going off it.

It's so complicated though - I'm sure if you are short on it it would be good, unfortunately that seems to be the case with almost all supplements and it's hard to tell what works with what...g
