Each hair strand relies on a sebaceous gland that secretes sebum to keep it hydrated. Factors like hormonal imbalances, very long hair (which weighs more and stimulates the glands), or an unsuitable shampoo can trigger overproduction.
To fight greasiness, many opt for harsh drying products. These irritate the scalp, leading to itching, dandruff, and faster re-greasing as glands respond to irritation by producing even more sebum. It's a vicious cycle.
Trichologists recommend gentle, purifying shampoos instead. These naturally regulate sebum, purify the scalp, and keep hair fresher longer without stripping essential moisture.
