my hair had gone very dry and frizzy and it felt dry on the length. After using my hair shark i immediately noticed a difference. It does encourage the natural oils in your scalp to make your scalp and hair feel healthier. Note when I run my fingers through my hair. It feels healthy and moisturised. The bristles master your scalp. I recommend this product to anyonne who has dry hair. Also the shape of the brush and the fact that it has a stap to put your fingers through make it easier to use. I have a problem with my hand and I find holding things difficult and this does ake it better for me to use my hairshark.
