How Hormones Change Your Curl, Wave and Coil Pattern at Every Stage of Life

Hormones are the most powerful non-productive force acting on curly, wavy, and coily hair, and the least discussed one in Indian curl education. The shape of the hair follicle, which determines whether hair grows straight, wavy, or coily, is not genetically fixed at birth and is not immutable thereafter. The body's hormonal environment continuously influences it. Androgens, estrogen, thyroid hormones, cortisol, and insulin each play documented roles in follicle geometry, keratin production, and hair texture. When these hormones shift, as they do at puberty, during pregnancy, after delivery, through perimenopause, and with thyroid or metabolic changes, the hair that grows from the follicle reflects that shift.For Indian women navigating changes in curl pattern, this is the starting point most content skips entirely.
