I wash my face ASAP after a swim/bike/run. Even if i have to pour water from my bottle on my face at the car after a ride, I will do it so i minimize the time sweat and salt stay on my face. Sunscreen a must. For face I use a baking soda/coconut oil mixture (paste) to scrub my face 3-4 times a week and only at night. At night I use my most expensive products like those containing Retin-A and other repairing vitamins, since the body heals at night. (dermatologist told me this). Love Philosophy products.
I also use African Black soap (find at Target or on Amazon) on my body. Eczema tends to pop up on me when its hot/humid and this soap absolutely keeps it at bay. I suggested it to a friend who tends to get a little body acne after hot/humid workouts and the black soap stopped it. ALWAYS lotion up after a shower. I like the Kiss My Face body lotions.
Hair; Aveda and Bumble and Bumble. My stylist began putting gentle gloss color treatments on my hair since its really long to protect the color from the pool water. Damage Remedy by Aveda is great for detangling and protects hair.
Hope this helps someone out there!
