Does whatit says

Yes, I recommend this

This product makes such a difference to my fine hair originally tried it in the small version in the Rewind box, it seems expensive but is likely to last a long time as only need to use it once a week or every other or so definitely worth the money

A worthwhile treatment mask

Originally posted on SMCK Hair Care Products Limited

This treatment doesn't have hugely volumising effect on my hair, but has some impact and also leave the hair feeling sufficiently moisturised. It also is has a detanbling effect if you use enough product.

This is my favourite hair treatment of them all! Leaves my hair looking amazing after I’ve applied this and left it on for at least five minutes. My hair is shiny and full. I use this treatment after my lighter cleanse shampoo and every three washes. My hair has never looked so good. Thanks!
