Hormones can have both a positive and a negative effect on the entire body, including the hair. Indeed, hormonal changes play a major role in the hair’s health and overall appearance. Shiny, full hair or dry, dull hair and
hormonal hair loss. Hormones are more critical than you think! It thus follows that contraception, such as the pill, would have a direct impact on the hair’s appearance, the main factor being the composition and dose of hormones contained in the pill. As these criteria vary from one pill to the next, hormonal contraceptives can have a negative or positive effect on the hair. Oral oestro-progestative contraceptives can have a positive effect on hair quality, whereas progestin-only contraceptives have a negative effect.
