What can strongly alkaline hair products potentially do to hair or skin?

Strongly alkaline hair products, such as certain hair relaxers and treatments, can have a significant impact on hair and skin because they raise the pH level, which can lead to damaging effects. The high alkalinity can disrupt the natural protein structure of hair, leading to the breakdown of keratin. This can result in both hair and skin experiencing burns or damage to tissue. Such products can strip the natural oils and moisture from the hair, leaving it dry, brittle, and more susceptible to breakage.

In addition, a high pH can irritate the scalp and skin, causing redness, sensitivity, or even chemical burns in severe cases. This underscores the necessity for professionals to carefully select products based on their pH levels and to ensure proper application techniques are followed to minimize the risk of damage to clients' hair and skin.

While other options might relate to hair care, they do not correctly represent the effects of strongly alkaline products. For example, providing intense moisture, enhancing hair color durability, or improving curl definition are not typical outcomes associated with alkaline products; rather, they can undermine hair health overall.
