This advantage from the plane of the health It was addressed by a recent study, where it was found that this is still transcendental today.
This is the importance of having curly hair
To find out if our hair evolved to assist early humans, scientists used a thermal dummy and a temperature-controlled, electrified human model to study how heat is transferred from the body to the atmosphere. They then directed the lamps at the mannequin’s head under four different hair conditions: no hair, straight hair, moderately curly hair, or very curly hair.
The research, carried out by scientists from the UK’s Loughborough University, calculated the difference in total heat loss between lamp measurements and base measurements to determine the influx of solar radiation to the head.

Consequently, it was shown how the various textures of the hair would affect the health. a mane with curls it protects the body from intense solar radiation that is expressed through heat.
