I have tried ECO-Style gel, you can get at any chain drugstore like CVS, Walgreens, rite-aid, etc and Sally's. Its a great gel its alcohol free and they have different varieties some with Olive Oil, & Argan Oil.
The issue with that it in the summer its great but for cheer season wont work, as her hair length is about ear length. If I blow dry it and fat iron it, its shoulder length. Problem is it wouldnt stay straight due to humidity, sweat and performance it will start to revert(go back to its curly state). Ethnic hair main problem is retaining moisture, our hair is constantly dry so trying to maintain moisture is key to styling hair etc.
I opted for braids 2 weeks ago. That way I can work with whatever style is determined for her team. I understand those parents who prefer not to chemically straighten hair, it is my choice at this time to not relax my CP hair. Im not comfortable with her getting a sew-in weave at 12. Braids are very versatile and can work with any style for cheer pretty much and keep cp age appropriate.
