Is Your Shampoo Causing Scalp Itching?

3. Product Build-Up: The Residue Dilemma

Shampoo is meant to cleanse, but if it’s not rinsed out thoroughly, it can leave behind residue that contributes to product build-up. This build-up can clog hair follicles and irritate the scalp, resulting in itchiness. If you notice a waxy or sticky feeling on your scalp, or if your hair feels weighed down, it could be a sign of product build-up. Using a clarifying shampoo once a month can help remove residue, but be cautious not to overuse it, as clarifying shampoos can also be drying.

4. pH Imbalance: The Acid-Alkaline Equation

The pH level of your shampoo plays a crucial role in maintaining a healthy scalp environment. Ideally, your shampoo should have a pH level close to that of your scalp, which is around 5.5. If your shampoo's pH is too high or too low, it can disrupt the scalp’s natural acid mantle, leading to dryness and itchiness. If you’re experiencing itchiness, check if your shampoo is pH-balanced. Switching to a pH-balanced formula can help restore the scalp’s natural state, reducing irritation and promoting overall scalp health.
