Yes, hormonal shifts may cause a couple of changes to your hair: 1. Hair Texture: Hormonal shifts can affect the texture of your hair. It might become curlier, straighter, frizzier or smoother. 2. Oiliness: During puberty, the production of sebum (the natural oil that keeps your scalp and hair moisturized) increases. This can result in oilier hair and sometimes contribute to scalp acne. Typically, these changes are temporary! As your hormones stabilize post-puberty, your hair will likely return to its previous state.
