Daniela Sommer at Deutscher Friseur, Las Canas (Sosua)
Suggested by DMV123 already, I would highly recommend Daniela's expert hairdressing skills.
I, too, have short hair and she cuts it just as I want and colours it too at very reasonable rates.
She is, however, off to visit her homeland for a month this coming Tuesday but if you are prepared to wait until her return w/c 9th May I am sure you, as many I have already recommended, will not be disappointed. Her telephone number for appointments is 809 974 3711.
