For coarse frizzy hair I would recommend the Moroccan oil which can be applied in small amounts on wet and dry hair. This will help smooth frizz and add shine and moisture. I will also recommend the L’Oréal techni art supreme smoothing cream for dry hair which is great for smoothing down frizz and adding moisture.
Alternatively a great treatment for frizzy hair is the brazilian blow wave. It smooths hair and takes away frizz and can cut down your blow dry time by 70%.
With regards to the hair shedding, naturally we all shed 50-100 hairs per day which are replaced by new hair. You could possible be experiencing an extended shedding period. A great new product that I can recommend to stimulate hair growth and thickness is the Kerastase Bain Densite shampoo and the Kerastase Masque Densite as well as the Kerastase Stemoxydine ampules to be used every day. This product is brand new on the market and it guarantees 30% increased hair growth after a three month course. There is also going to be a in salon treatment in this range.
