In regard to hair texture, what is the significance of coarse hair during the dyeing process?

Coarse hair has larger diameter strands and a rougher cuticle layer, which contributes to its ability to absorb and hold onto dye. During the dyeing process, it may not react to color in the same way finer hair does. This can lead to a situation where coarse hair may achieve a lighter final result than anticipated, particularly if the developer used is too strong or the color formula is potent. This is due to the way the cuticle scales lay down over the hair shaft and how they open when subjected to chemicals. Coarse hair often requires specific formulations or adjustments during the coloring process to achieve the desired color outcome effectively and accurately. Understanding this aspect is vital for professionals to ensure that the client's expectations match the actual results during and after the dyeing process.
