Widely recognized for her expertise in Botox, neurotoxins, and facial injectables, Dr. Durairaj was voted one of the top 100 injectors in the country by her peers and hosts the podcast Beauty Bytes with Dr. Kay.

Dr. Durairaj explains why hair is often the body's earliest warning sign of an underlying imbalance, and walks through how she diagnoses the root cause before turning to regenerative treatments like PRP and exosomes to restore hair health.

"I think hair is in many ways like the canary in the coal mine. It's the first indication that things might be going wrong in the body because it is such an accessory ancillary organ... I do think that the hair is an external indicator of that internal health."
