What Stress Really Doesto Your Skin and Hair

When stress hormones rise, your skin’s barrier weakens. Cortisol breaks down collagen and slows cellular repair, leading to dehydration, inflammation, and dullness. This is why your complexion might lose its brightness or feel more sensitive after long, high-stress periods. Environmental shifts — travel, cold weather, or lack of sleep — amplify this effect. They create oxidative stress, which drains the skin of radiance and elasticity. The result? Fine lines, redness, and that hard-to-define sense of fatigue that even makeup can’t mask.

Hair and scalp health are equally sensitive to stress. When the body feels pressure, blood flow to the scalp decreases, and hair follicles shift prematurely into the shedding phase. For men, this can accelerate thinning; for women, it often shows as diffuse shedding or scalp sensitivity. Hormonal imbalances, especially around the end of the year or during lifestyle changes, intensify the issue; a perfect storm of physical and emotional strain.
