CurlySuzy offers several suggestions

Dear CurlySuzy: I'm looking for a product suggestion to really work with the sides of my hair like a gel but not damaging for natural hair.

Dear De'Anne: Here are some gels that are healthy for natural hair. I hope this is what you are looking for. Please email me again if you have more questions.

This is a great gel, follow styling instructions exactly for best results:
Curl Junkie Curl Assurance Aloe Fix Hair Styling Gel

This will work best, I think, with a leave-in conditioner under it. It is lighter than the one above:
Curl Junkie Curls in a Bottle

This is another medium-light gel:
Jane Carter Solution Condition and Sculpt

This is heavier. I am not sure what the texture of your hair is and how much weight you want:
Blended Beauty Happy Nappy Styles

Great leave-in conditioner that works great with any product over it:
Kinky-Curly Knot Today

This is a very unique product:
Kinky-Curly Curling Custard
Only works well with the Knot Today It is a very thick gel, and has to be applied on very wet hair with the Knot Today already in your hair. Very, very concentrated; if you use too much, it will be sticky and super crunchy.

This is like a gel and a cream mixed together:
Oyin Handmade Shine and Define
