For more information on a fantastic natural product line - please visit my web-store at https://www.infashionsense.com and click on the 'HERSTYLER INFO' button and read more about HerStyler natural minerals hair irons and dryers and natural plants-protein %26amp; olive oil hair care products. I'd suggest a complete daily regime of proper NATURAL care for fantastic healthy hair all the time, the HerStyler shampoo, conditioner and styling spray (if you use spray) daily, the mask is a must for deep conditioning for healthy hair it repairs dry, damaged or frizzy hair caused by environmental/pollutant damage, chemically treated hair damage and styling tools damage, and the serum is an absolute must while styling to protect from styling tool damage, and give silky smooth and shiny results and hold your hair style all day through any weather! Great products are economical also, as you only use a tiny bit! I hope this is helpful - please email or use the chat on our store for any further questions - all the best!
Tigi Brunette Goddess. It is expensive but you need very little to wash your hair (as it's so rich) so it lasts forever. You can get it in most hair salons.
