Alopecia and insomnia

Using the fingertips of both hands, massage your scalp vigorously with small rubbing or gentle scratching movements.
For a more stimulating effect, use your nails to gently 'scrape' the scalp without hurting yourself. First cover the area from the forehead to the nape, then from the temples to the nape.

Press hard enough to feel the scalp moving.
You will notice how gradually the blood circulation throughout your head reactivates: a pleasant feeling of lightness and freshness, especially upon waking.
