Sorry, hair dye without any chemicals is just not a thing (again, unless you're working with henna or straight-up plant juice). Dye will always require some chemical-based ingredients to help deposit pigment onto your hair.
In short—the answer is yes. For starters, the hair color offered in at-home varieties is of a lesser quality than those you find in salons. This is because they contain harsher, more concentrated chemicals and often skip out on the protective ingredients used in a salon setting.
It's not impossible to have a healthy head of dyed hair. Even though dyeing does do damage to your hair, there are plenty of tips and tricks that can mitigate the damage and return your hair back to its natural, healthy state as much as possible.
Perhaps the most toxic ingredient, PPD (paraphenylenediamine)—rated seven out of ten in terms of toxicity on ewg.org—is in most permanent hair color (some contain a similar compound, PTD), including many so-called organic and natural formulas.
Generally, it's safe to re-dye every 6 to 8 weeks. Permanent hair dye lightens the hair and deposits color.
All-over color is usually cheaper than highlights because it takes less time and work. Highlights also are more likely to damage your hair. Many of the formulas for highlights contain bleach, which dries out your hair.
Resorcinol found in hair dyes is a phenol derivative, which may also contribute to renal toxicity. In addition, a few hair dyes also contain lead acetate and Bismuth sulfate, which can cause chronic kidney disease or acute interstitial nephritis respectively.
Are salon hair dyes better? Simply put, when it comes to salon color vs. box dye, it's always best to get your hair colored at the salon by a professional. Salon formulas better for your hair, and having a pro colorist apply it also ensures the best results.
Hair dye does not stop or even slow down hair growth, but it can cause hair loss by damaging the color-treated hair. The chemicals in hair dye can cause some of the damage.

They typically contain high amounts of ammonia, PPDs, nitro dyes, metallic salts, and even unclean henna. These are harsh chemicals that can be extremely damaging to the hair as well as cause reactions to sensitive skin and allergies.
For grey hair coverage, we generally recommend that you aim to color slightly lighter than the natural hair color level of your client. In this case we would suggest you go for a color starting in level 6 (Dark Blonde) or 7 (Blonde).
If your hair starts to feel increasingly dry, brittle, or damaged or you experience scalp irritation, it might be time to ditch the dye.
Demi-Permanent or Semi-Permanent Color
While a demi-permanent or semi-permanent hair color can be applied to any level of gray, it's often used to camouflage early grays, giving 30-70% coverage.
The chemicals used are only absorbed by your hair, and not by your scalp or bloodstream.
So through our skin or hair follicles, compounds in hair dye could get into our bloodstream. That's potentially worrisome, because a lot of the chemicals in hair dye are known or suspected to be linked to health issues.
The Bottom Line. Even when hair dyes are used correctly, they can cause toxicity. Skin damage and allergic reactions are well documented. Eye exposure can cause a range of toxicities from mild irritation to loss of vision.
Harsh shampoo, hair treatments, styling products, and excessive brushing contribute the most to poor hair health. However, other culprits include: overconsumption of alcohol. low-calorie and crash diets.
