Relaxed hair - damaged in one section. Can it be relaxed again? Professional in San Diego needed!

Top of head of hair burned by relaxer, so I'm growing in a mohawk. Areas of hair peripheral to this look slightly damaged but have not fallen out despite pulling on it with a brush while blow-drying hair. Can hair be relaxed again in three months? My hair is thick and generally not prone to damage. It's been relaxed repeatedly by a salon (whose hairdresser I'd like to ...) with relaxer that has overlapped a previously relaxed section without subsequent damage. The type of relaxer used was thio-based by Esuchen. The hairdresser was in a rush and left the product on too long.

Can anyone suggest a salon or hair stylist with experience in relaxing hair, that is located in San Diego?
