AlpecinC1 Caffeine Shampoo, 8.45 fl oz, Cleanses the Scalp to Promote Natural Hair Growth, Leaves Hair Feeling Thicker and Stronger

It's not sulphur free unfortunately but I feel it works to grow hair length only while using the product then hair stops growing.

It definitely leaves your head squeaky clean. As far as effectiveness of this caffeine shampoo it might be too soon for me to tell because I only been using it for a little under months now. I am also using minoxidil for hair growth. I do have some little hairs growing in but I can't tell whether it's the shampoo or not. I will say that it does take having a clean and healthy scalp to grow a good head hair.The smell is kind of medicated but it doesn't really bother me, it's not too strong.

I love how it makes your hair feel refreshing and it has helped with my hair loss.

I am very pleased with this product.

No clue if this works..been using it everyday.

Very nice

Recently, I noticed that I was getting acne on my forehead. I initially thought it might be due to a change in my diet or food. I visited a dermatologist who prescribed a shampoo to use before my main shampoo, which was same product at the time. She also recommended a pomade. However, those treatments didn’t work for me (as I was still auing this shampoo).When I went out of town, I forgot to bring the shampoo, and I noticed that my acne cleared up! Afterward, I did some research and found that several people on Reddit mentioned having a similar experience.

Very nice shampoo leaves scalp tingling and seems to have halted hair loss
