Less hair fall
I'm very skeptical when it comes to products that claim to help with hair loss so I wasn't expecting this product to actually help, but it did within two weeks of usage.

Hair thinner than it was before
I have been struggling with hair thinning and sheading, with processed and bleached hair. I used this product for 9 months and did not notice any hair thickening or re-growth. If anything my hair feels more brittle, thinner, and I am still experiencing the shed amount each day. I will note that the product, shampoo especially, lasts a long time- a little goes a long way. The conditioner is average. And the tonic foam does cause temporary scalp redness.
I have used this shampoo and conditioner for years.
I have used this shampoo and conditioner for years. I like the refreshing mint scalp invigorating scent. Getting the set on sale was a good deal!

Not for me
Used all 3 products in the conditioning kit for 2 months and did not notice a difference with fallout. Hair looked dry and lifeless.
