Do you all know washing of hair? i bet some people long long wash one time their hair very unhygienic man. Let me start on it. First you need to know what type of hair you have? you have oily, dry, weak,hair loss, dandruff, allergic, brittler. Then buy the suitable shampoo for your hair. Slowly even if you dunno your type of hair. If the hair making you itchy it doesn't suit you throw it away. Washing of hair also have it's own way.wash your hair you must put some shampoo on your hand the right amount, add water and rub with the other hand. It's ready when foams are formed lar, then can wash your hair. Because if you wash your hair straight away, your hair definitely will spoil, cause too strong for the part which you apply on. Which will leads to hairloss. So form foam first. Then when wash you must make the whole head , which mean sunburn your back. Then wash it with warm water lor. not cold cause if too cold your hair will contract too hot also cannot. Wax, spray and everything not too much, enough can le, preferably 1 finger size can make your hair le. And for at most one day only can wash hair twice not too much! washing too much not good for your hair also. ok nothing more to write le byebye
