I had great hopes for hair improvement.
I am not sure what to make of this product.  The more expensive brand was suggested by my dermatologist and was told it would be 6 months to a year to show any improvement or difference in my hair.  She was correct.  At about 5 months or so it was clear that my hair was growing faster and less was falling out, but no new growth.  It has been over a year now and still no new growth, but the texture of my EXTREMELY fine hair is slightly better, BuT  for whatever reason it no longer holds a permanent.  Other than the usual dryness that a new perm brings, no curl held.  I am still deciding if I will continue it as I have been a life time perm user just to add some body and volume to my limp fine hair.  I have also realized my nails have grown faster, but again not any stronger.  I dont think it is the product per se, but it hasnt worked for my particular hair type in the way I was hoping,  which is very disappointing.
