Sometimes I hear "my hair texture is different" and so this or that person feels they need to avoid washing so that the new Locs don't unravel. You might want to get a pen and paper for this next part; all new Locs unravel. LOL! Especially so for mixedrace hair, trust me I'm mixed with everything you can think of and "they" told me my hair would never Loc, because of the texture. But I tried my best to leave it alone, I washed it once a week, and in 4mos I was official.
Think of your new Locs like a plant, a mighty tree with strong roots. It is a cultivation. It requires, care, patience and a positive attitude. Your hair needs to be clean so that your scalp can get the oxygen and sunlight it needs to grow, and so that the hairs have enough "grip" to form the knots that create your Loc shaft. It takes time.
After having all kinds of gunk put into his Locs and being advised not to wash his hair for a few months, check out this client's testimonial below talking about his SteamWash'n'Loc experience after 2months of not washing.
