Hydrocortisone is a mild corticosteroid that reduces inflammation and itching. It sometimes comes up in hair loss discussions because an inflamed scalp can be uncomfortable and can affect the hair. This guide explains the connection and the limits of what a mild steroid can do.
How scalp inflammation relates to hair
Conditions such as seborrheic dermatitis, psoriasis and contact dermatitis (a reaction to hair products or dyes) can cause redness, itching, flaking and discomfort. Scratching and inflammation can damage hair and contribute to shedding. Some forms of hair loss, including certain scarring alopecias and alopecia areata, are themselves driven by inflammation and need specialist care.
What hydrocortisone does
Low-strength hydrocortisone is available over the counter and can calm mild itching and redness for short periods. It does not treat pattern hair loss, and it does not regrow hair. In hair loss care, a provider may occasionally include a mild steroid in a formula to help the scalp tolerate other treatments, but that is a clinical decision. Compounded medications are prepared by a licensed pharmacy for an individual patient and are not FDA-approved.
Using it safely
- Use only for short periods unless a clinician advises otherwise. Long-term steroid use can thin the skin.
- Do not use on broken or infected skin.
- Stronger steroids for conditions such as psoriasis or alopecia areata are prescription treatments and need a clinician's supervision.
When to see a doctor
See a doctor, ideally a dermatologist, for scalp pain, burning, pus, a spreading rash, scaly plaques, patches of hair loss, or a smooth shiny area where hair has been lost, which can signal scarring. Scalp inflammation that does not settle with gentle care needs a diagnosis. See common scalp issues.
