In-growing hairs can be a real problem. An ingrowing hair is one that curls back on itself and grows back under the skin. Some hairs continue to grow along the surface just beneath a fine layer of skin and can be seen quite clearly.
Generally they occur more around the neck and jaw line and are usually more common on Afro-Caribbean skin.
An in-grown hair will cause a bump and sometimes they can become infected and sore or even become a cyst.
The best way to prevent in-growing hairs is to shave in the direction of hair growth and not against it. Shaving against the grain can distort the follicle and scalp the hair too close to the surface of the skin, making it easier to in-grow.
Use a gentle face scrub regularly to remove dead skin cells and to help release trapped hairs.
Moisturise to keep skin supple and to encourage hairs to grow through unhindered.
Ensure you follow a good shaving routine as, over time, this will naturally reduce the chances of ingrowing hairs (and give you a great irritation free shave too).
