This is Jennifer Cherilus. She's an award-winning NJ-based hairstylist who specializes in all things natural hair care.

She can do lots of styles, but it's her gorgeous protective styles that keep clients (like me!) coming back for more.

You'll never make this mistake again after reading this.
Yep, Jennifer does my hair too. Every black girl knows that finding the right hairstylist is harder than finding your soulmate, so shout out to God.
She also recommends a good shampooing at four weeks—the halfway point—to try to remove some of the build-up that’s already accumulated. For those people worried about the hair swelling and getting frizzy post-wash, you can try cleansing your scalp with an astringent like Sea Breeze. But keep in mind that they typically contain alcohol, which tends to dry hair out, so you’d have to immediately start your moisturization regimen again right after using it.
"When you leave any hairstyle in too long, there's nowhere for those oils, skin cells, and shed hair to escape. So those things sit underneath your wig, your sew-in, your crochet braids—whatever style—and they start to build-up on your scalp."
"At that point, you’ve opened yourself up to serious scalp infections, mold, and even egg-storing bugs and insects," she added. (The latter’s not common among African Americans, but that doesn’t mean we can’t get them.) And Jennifer's witnessed these super scary results herself, having seen people's scalp turn colors, like gray and green. "When it gets to that point, the only solution is really cutting off all your hair and starting over," she said.
