No noticeable improvement after a year
This hair serum has not smell and easy to use. However, after using this serum diligently for over a year and did NOT see any noticeable improvement in thickening my hair, I will probably discontinue buying this serum when I finished my current inventory. . . considering the price.

Silvessa Hair Serum
I love this hair serum. It helped restore hair loss post menopause that is so heartbreaking for us. Once we had beautiful hair, then it changes, and frankly nobody warned this would happen when I was going into my physicians office for post menopausal care. It absorbs beautifully, leaves your hair ready to style within a few minutes.

OK-- I really like this
I have used one bottle and on my next--I talked to my hairdresser and my dermatologist and they both thought this was a great product. After 6 weeks of use, I went back to hair dresser and I saw some new growth on the top of my head--I said, did these hairs break off or are they new hairs-? She thought it might be new growth! WOW! yay! I will continue to use for at least 3 months, but so far, so good.
