I had a big issue with smelly hair syndrome for almost 2 years. It was a nightmare and I tried absolutely everything, from natural remedies to medicated shampoo from the doctor. Nothing worked in the slightest.
Then I was given strong penicillin antibiotics a couple of months ago for something else (swollen fingers from coronavirus! ) and it has totally cured the smelly hair issue! I am so massively relieved.
