According to Dr. Amit Bangia, a dermatologist at Asian Hospital (India), deep cleansing shampoo is designed for uncommon use. This shampoo has a strong formula, helping to remove excess oil and residue from styling products such as gel, hairspray or mousse.
This is why deep cleansing shampoo is especially suitable for people who regularly style their hair or are exposed to chemical environments, such as swimming in chlorine-containing water.
However, its strong cleansing ability is also a double-edged sword. Deep cleansing shampoos often contain a high level of surface activity, easily sweeping away the natural oil layer protecting hair and scalp.
If used too often, hair can become dry, brittle, easily broken, and the scalp can become dry, itchy and unbalanced.
Regarding the frequency of use, Dr. Bangia recommends once a week, depending on the hair condition and personal care habits.
For people with dry or sensitive scalp, the frequency should be reduced to once a month or even every six weeks. Deep cleansing shampoo should not be seen as an alternative to regular shampoo in the daily hair care routine.
To limit side effects, experts recommend using only a small amount of deep cleansing shampoo on moist hair, massage gently and then rinse thoroughly.
Using conditioner is then necessary to replenish moisture and help hair become softer and smoother. People with scalp problems such as psoriasis or seborrheic dermatitis need to be especially careful, and should even consult a doctor before use.
Deep cleansing shampoo can bring clear benefits in cleaning hair and scalp, but is only truly effective when used correctly and in the right frequency. For dry hair and scalp, caution is a key factor to avoid more harm than good.
