2. Shampoos containing silicones can cause hair loss, shedding, and itchy scalp. Opt for silicone-free formulas whenever possible.
3. Avoid direct contact of shampoo and conditioner with the scalp. Improper application can clog pores, leading to mild conditions like seborrheic dermatitis or severe hair loss.

4. When combing, keep the hair and scalp perpendicular to avoid damaging hair follicles and pores. Apply more pressure when combing dry hair, but minimize force on oily hair—excessive pressure can stimulate increased sebum production.
