Could hair dye cause hair loss?

I've been tracking my hair health and scalp condition on my wellness app, and ammonia-based dyes definitely cause chemical damage that leads to thinning. Try scanning product ingredients before buying and look for ammonia-free alternatives.

Don't fall for internet claims about onion juice or organic dyes fixing everything. If you are experiencing severe hair fall after using a dye, it could be an allergic reaction or scalp dermatitis. Go see a proper dermatologist instead of trying home remedies.

Dyes might cause surface damage, but hair fall is often linked to internal stress or blood pressure issues. I noticed my hair thinning when my BP was high. Get your routine health checks done alongside changing your hair products.

I used a cheap box dye last year and my hair started falling out in clumps within two weeks. I immediately stopped coloring my hair and focused on basic care. It took almost six months for my scalp to recover.

From what I see at the clinic, cheap hair dyes with high paraphenylenediamine (PPD) levels can irritate the scalp and cause hair shedding. Always do a patch test behind your ear 48 hours before applying any color.
