Can Hair Dye Cause Hair Loss?
Quick answer: Hair dye does not cause pattern hair loss, but harsh chemical processing can make hair break, and allergic reactions to dye ingredients such as PPD can inflame the scalp; patch test before colouring and avoid over-processing.
- Breakage: Looks like thinning.
- Allergy: Patch test.
- Grey and thin: Grey vs thin hair.
