What is one risk of using harsh chemical treatments on hair?

Using harsh chemical treatments on hair can lead to scalp irritation due to the aggressive nature of these products. Many chemicals, especially if they are alkaline or involve strong acids, can disrupt the natural pH balance of the scalp. This disruption can result in inflammation, redness, and sensitivity.

Moreover, the protective barrier of the skin can be compromised, allowing for irritation not just from the chemicals themselves but also from exposure to environmental factors. This underscores the importance of understanding how these treatments interact with both the hair and the scalp; while they may promise aesthetic improvements, they often come with significant risks that need to be managed properly. It's essential for practitioners to educate clients about potential side effects and provide them with alternatives that might be less damaging.
