This was a very popular hairstyle in the late 1950s and involved applying lots of gel to the hair and brushing it up around the front of the hairline as well as in back. It was adopted from African American youth who grew up their hair and gelled it up. It was also known as a flat top.
Daily Hair Tip
Whenever possible limit or avoid using a brush on curly tresses. Instead use a widetooth pick or comb with "hair friendly" edges that won't rip or tear fragile curls.
