How many units of lye are typically needed when performing a blend treatment for thick coarse hair?

In electrology, particularly in blend treatments, the amount of lye used is crucial for effectively targeting the hair follicles, especially when dealing with thick, coarse hair. Thick hair requires a higher amount of lye because it has a more robust structure that is more resistant to chemical decomposition. Therefore, a range of 40-50 units of lye is typically considered ideal for achieving the necessary chemical reaction to effectively treat this type of hair.

When performing blend treatments, which combine both electrolysis and galvanic techniques, the lye produced helps to soften and break down the hair shaft and surrounding tissue, facilitating easier extraction of the hair. The higher unit range ensures that there is enough lye generated to manage the particularly strong and resilient characteristics of thick, coarse hair effectively. This understanding is critical for electrologists when planning treatments, as using insufficient lye can lead to ineffective results and prolonged treatment times.
