Mine is HORRIBLE! Never had it coloured or anything, was a lovely deep auburn, natural redhead!
It's now a darkish brown, is coarse like like straw and is coming out literally in handfuls. I had it washed on Sunday and with one brush, out of my head came more hair than if I had brushed my Golden Retriever! A fistful of it ... I am unwell and on a massive load of strong medication, and it has been coming out for quite a while, but not this much! At least it is still growing ... and at 61 there's only a small smattering of white ones, but it was the best thing about me.
Hairdresser has recommended
"As I Am Coconut CoWash Cleansing Conditioner 16 oz." which you can get from Amazon
... and Argan Oil as suggested above many times!
