Relaxed Hair: Relaxer Stretching
The area separating these two textures is called the "line of demarcation" and represents the most fragile spot on the hair during stretching. This particularity requires special attention to this area and to new growth, which needs stronger hydration for maximum elasticity to reduce dryness and breakage. The longer the stretching period, the greater the need for hydration for the entire hair. Although this period is also essential for a healthy scalp, it is important to pay attention to the overall condition of the hair throughout the stretching, as poorly managed or excessively long stretching can lead to breakage. Optimizing stretching means paying particular attention to new growth and the line of demarcation (with hydrating care), but also being gentle with your hair by maximizing protective hairstyles and reducing manipulation.
