Dyeing hair doesn't damage it at all, if anything it nourishes the hair. It's bleaching the hair that damages it. And I'm not bleaching it
HOW DYE AFFECTS YOUR HAIR
Hair dyes contain a cocktail of strong chemicals, so its no surprise that frequent use of them could damage hair.
Dyes can include chemicals like:
Ammonia Hydrogen peroxide, and Sensitizers like Paraphenylenediamine (PPDA)
Each of these chemicals may cause problems, from drying hair out, to leaving it brittle and prone to breakage.
They actually do this working as a team. Ammonia allows the dye to penetrate the shaft of your hair by swelling it and lifting hair cuticles, the protective plates that cover hair. Hydrogen peroxide destroys your hairs natural color, while also drying it out.
The chemicals also strip away hairs natural protective lipid layer, leaving it exposed to future damage and feeling rougher
Dyes used as color additives bring their own challenges. Sensitizers such as PPDA in particular are known as a common allergens.
Combined, these ingredients can be very damaging indeed, even causing hair loss due to breakage over time.
HOW DYE AFFECTS YOUR SCALP
Unfortunately, the damage doesnt stop at your hair. Frequent scalp exposure to the chemicals used in hair dyes can bring its own problems.
These chemicals can remove the protective lipids/oils from your scalp, leaving it exposed and vulnerable to damage from the environment, styling products and other irritants.
You may see these symptoms:
Stinging Scalp itching due to skin irritation Swollen patches Red skin
Actually, semi permanent dye has none of those ingredients. And I'm using that kind of dye

Eh, bleaching the brown part won't do much damage. I have a lot of oils and deep conditioners that would help
That's good. I'm all about the hair science and healthy care! I have very coily curls naturally, so the bleach really loosened and straightened them out. I was going to re-dye it blue, but I got a job that forbade it. I may dig up a pic...
