Hello Lavandula,
Whilst studying reflexology I had a case study who suffered alopecia (I can't remember the name of her condition but it was an auto-immune disease). Her hair would fall out and grow back randomly.
I gave a general treatment with emphasis on liver and thyroid reflexes. I also had her rub the nails of her fingers together as suggested in Beryl Crane's The Definitive Practitioner's Manual. My case study did report that her hair seemed to be growing back quicker.
Hope this helps
Wesam
