Deirdre Mills –
After using Liss Unlimited Shampoo during my salon visit, my frizzy hair became much smoother and more manageable. The Pro-Keratin formula really made a difference in reducing flyaways and improving shine. I noticed the effect lasting for several days after washing.
Alexander Rutherford –
The shampoo works well for my curly, dry hair. It doesn’t leave a heavy residue and helps control frizz without making my hair feel stiff. I recommend it to anyone with unruly hair types.
