Worked for me
I have used it from July to now early Sept. it has made the hair on top on my head grow back. I had been using another shampoo system for past 8months that slowed down hair loss but didn’t promote new growth and stripped the colour out. This keeps the colour and new hair is slowly coming back

Ok
Bought on prime day thinking it was a bargain but it was cheaper the next day ? I’ll be more careful next time

This really works well
After having covid pneumonia my hair started falling out and became very thin, so much so that I nearly bought a wig I've been using this for 2 months and the result is brilliant, it's growing again and becoming thicker I

Easy to use. Love the smell. Will keep using this. Don’t like the price!!!!

Doesn't work for me
I have tried this for many months and cannot say I see any real difference. Expensive considering no noticeable results.

Awful shampoo
Tooo expensive just to damage my hair!!!! The shampoo is awful and the tonic (leave the hair super dry! The opposite of good). only good was the conditioner

I didn't know that this product existed until I complimented a stranger on her hair and how shiny it looked. She got really excited and told me about this product and how it saved her and her mother's hair. I ordered the Level 4 because I dye my hair blonde. I believe she was a level 1 because her hair was natural and dark, never dyed. I love the way the shampoo smells . There is a slight tingly feeling because of the peppermint, but it was invigorating. I noticed immediately upon blow drying that my hair seemed softer and it was easier to style and a little goes a long way/ It did appear to be cleaner too, revealing a shine that I didn't experience with the other products I've used int he past. I can honestly say that I intend on using this shampoo long term and hope to experience longer and healthier hair with prolonged use. I was pleased with the amount of shampoo and conditioner that was in the bottles. I'm sure it will last me a good couple months until my next purchase!

This is a good product. Comes in a set. However, I had to complain about the Leave-In Treatment bottle that was not a full bottle (almost half full) ...The seller was also quite helpful, but unfortunately had to request a claim as I was unhappy about the Leave-In Treatment bottle in the box. I purchased 2 sets & both Treatment bottles were half empty. Thanku Amazon for the efficient after sales service. Still a happy customer 😊
