If you use hair dye too often, it strips all of the nutrients from your hair which can lead to an irritable scalp and may cause an infection. Use a soothing shampoo until your head doesnt feel sore anymore and be careful with how often you dye your hair!!
I have my hair dyed at salon which have for many many years now I have started to get a very sore and itchy head is there a brand you could recommend my natural colour is now grey
Hair dye can often cause allergy. Sometimes the allergy doesnot show up during the first or second application but repeated dyeing of hair can result in allergies. The cause is usually presence of para-phenylenediamine (PPD) in dyes. You should immediately consult a dermatologist. And use Natural Henna in future for dyeing your hair.
