Hello. Thanks for writing to us at healthcaremagic
These bald areas are most likely patches of Alopecia Areata(AA).
Alopecia Areata(AA) is an autoimmune condition. It usually presents as smooth bald patches of hair loss, most commonly over the scalp.
The patches of Alopecia Areata are smooth, and usually there is no evidence of inflammation like scaling or erythema or itching.
Intra-lesional depot preparation of
Triamcinolone acetonide is the treatment of choice in adults.
Patchy alopecia areats is a self limiting though new bald patches may appear, which may also need to be treated in the same way.
Other topical treatments that have been tried either alone or in combination with intralesional steroids are Topical Potent steroids ( e.g
Mometasone Furoate,
Clobetasol propionate); Topical
Minoxidil solution; Topical Anthralin; Topical PUVA(psoralens +UVA therapy) etc
I would suggest you to visit a
dermatologist for a confirmatory diagnosis as well as discussion regarding the most appropriate treatment for the bald patches
