Why does the keratin dry out your scalp after use?

Keratin treatments can dry out your scalp because they often contain high levels of formaldehyde or other harsh chemicals that strip natural oils from the hair and scalp. Additionally, the intense heat used during the treatment can further dehydrate the scalp, leading to dryness and irritation. Over time, this can disrupt the scalp's natural moisture balance, resulting in a dry and uncomfortable sensation. To mitigate this, it's essential to follow up with moisturizing products and practices.
