Why do beauticians dip braid d hair in hot water?

Beauticians dip braided hair in hot water to set the style and enhance the longevity of the braids. The heat helps to seal the hair, making the braids more defined and reducing frizz. Additionally, hot water can help to soften synthetic hair used in braiding, allowing for a more natural look and feel. This technique is commonly used in styles like box braids and cornrows.
