Pre-dive: (1) apply deep-conditioning treatment to dry hair then make a low braid - I used Moroccan Oil Intense Hydrating Mask. (2) Keep braid protected from wind and sun, especially on boat where winds are high. Whilst diving: (3) wear a hood... it doesn't matter if its cute or not. I'd rather protect my hair whilst diving to be cute when on dry land. Does anyone look cute diving?? Uh, no. Post-dive (4) unbraid, freshwater rinse followed by gentle towel-drying, a COMB, not a brush and spray-in conditioner.
