Tracey MacLeod –
Used this shampoo regularly after a salon keratin treatment. My hair feels smoother and less frizzy every day. It doesn’t dry out the strands and gives a nice shine without weighing the hair down. Very satisfied with the results.
Thomas North –
My hair has been treated at the salon and this shampoo helps keep it sleek. It’s gentle and doesn’t make my hair feel stiff. I notice less frizz after washing, especially in humid weather.
Fiona Robertson –
After switching from a regular shampoo, I see a noticeable difference in how my hair styles. It’s easier to blow-dry and straighten. The conditioning effect is strong and leaves hair soft and manageable.
Charles Dyer –
It works well for maintaining smoothness, but I found it slightly less effective on very coarse hair. Still, it’s a good option for daily use if you have already had keratin treatment.
Jake Black –
I use this shampoo every day and my hair stays frizz-free and shiny. It feels like a maintenance routine that keeps the salon results going for longer.
