I comb everyday!!
I have 4 combs: General wide tooth, fine tooth, wide tooth w/skinny handle, and wide tooth shower comb.
General wide tooth - this is my daily styling tool. I use it to comb the body of my hair (never the new growth) after moisturizing and sealing.
Fine tooth - I also use this everyday for my ends only after I put moisturizer on them. The fine tooth comb removes any shed hair that may be lurking there and also gives my ends a smooth look. After a wash/cowash, I use my fine tooth comb after I've applied my leave-ins, but before I put on my scarf to airdry. I use it on my front edges only to smooth them down for a sleeker look once dry.
Wide tooth shower comb - used in the shower as I comb out conditioner.
Wide tooth w/skinny handle - I only use this comb after I wash/cowash to put my daily part in my hair. The skinny handle is perfect to get through tough/wet newgrowth.
