Urban company has good services and all precautionary measures are practiced well by them
I went to Geentanjali in Punjabi bagh and I had a great experience. Every possible measure was taken from sanitising the seats to providing shoe covers. Even though the precautions are being taken, I suggest that you only visit a salon if there is any urgent need.
I don't know about your region but in my locality (Rohini) the barber wears gloves and a face shield with a face mask and a long gown. All sanitized and provides you with a use and throw gown. All the equipments he uses are also sanitized. So very safe experience
