My DS has had a smart new hair cut this week which involves sweeping his hair over to one side as per pic attached. Struggling to find the best product to keep it in shape though. Gel doesn't seem to work as if he touches it it sort of cracks and vanishes. Tried DH's matte clay (by Shockwaves I think) but that doesn't have the staying power throughout the day. Any recommendations for something which might do the trick please?
