Well I never thought id justify a shampoo over a t
[This review was collected as part of a promotion.] So my hair is normally prone to frizz and looking like a boff head as my kids like to say, but my hair has been puffy free and frizz free and feels like ive been to a salon. Quite pricey but I used it once a week around my normal hair care highligly recommended

Great shampoo for frizzy hair.
[This review was collected as part of a promotion.] Loved this product. It lathered up really well and helped to smooth out my frizzy hair. Once blow dried, there was noticeably less frizz and my hair appeared smoother.

Lovely smell but greasy residue
[This review was collected as part of a promotion.] Washing my hair with this shampoo, it lathered up well and smells beautiful. When rinsing, it seems to make your hair feel lovely and soft. Unfortunately, after drying my hair, either leaving it to naturally dry or blow drying, it left a bit of a greasy residue and greasy look about my roots.

Salon like hair at home
[This review was collected as part of a promotion.] I loved its gentle cleaning formula I.e without any sulphates. It has controlled my frizz making it shiny and silky. The smell is beautiful which gave me salon like feeling. It is best for dry damaged and frizzy hair as this gives that sleek feeling and smoother hair. Hair was easier to manage after shampooing. I loved it.
