When I initially started CG my scalp and hair loved it, but after about 3 months I had patches of very bad flaking and itchiness. It took a lot of trial and error to work out that what caused mine was leaving in most of the second dose of conditioner.

Now I rinse it out completely then use a leave in and my scalp is happy again

Modified CG - Suave coconut conditioner (CW), BC Down and Out, and and Aussie MM conditioner my current loves.
