Infection in the head due to dirty comb, itching: after grooming the hair, do wash the comb, and change it every 6 months

Yes, washing your comb regularly after grooming and replacing it every 6 months can reduce your risk of scalp infections. When you use a comb, it combs your hair follicles, and if it’s not clean or it’s too old, it can lead to bacteria and fungus growth. So, make sure you clean your comb regularly and use new ones.
