also I need some advice on my mums and sisters hair care, my mums hair is very coarse ,thick,frizzy , very dry, brittle and it's coloured , we don't do much major to it like she has permanent colour on her regrowth every 4 weeks and semi colour on her ends , we only blowdry never use the irons on it , she does re-shape her fringe with a round brush everyday but uses a heat protection product when she does it , we have tried most products even products for Afro hair and still it's stays dry, brittle and difficult to make smooth and shiny what products would you recommend?
