A colour hair rinse that isn't permanent doesn't penetrate the hair shaft, so is the perfect solution for anyone looking to dye their hair without causing breakage or damage. There are many shades available, but because these rinses don't contain strong chemicals or bleaches, don't expect a dramatic colour change.
Semi-permanent: Coats the hair with pigmentation with a developer that lasts a few weeks to a few months. Begins vivid, but fades over time. Good for short periods, non-permanent, and less damaging results.
To minimize damage, your best bet is to stick with a neutral color that closely matches your hair. The one exception is for redheads, who should look at the warmer colors available. And if you're torn between two colors, remember: You can't necessarily trust the model on the box—these images usually skew lighter.
“Does box dye damage hair?” Yes! Box dye is not formulated to the same standard as professional hair colour. Salon hair colour costs more because it is better quality. It doesn't contain so many harsh ingredients and often works to protect your hair as it colours.

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.
Blonde is usually the hardest on your hair's health. That's because in order to lighten hair you have to strip pigment from it, and that requires ammonia and peroxide — two of the most damaging chemicals in hair dye. The more solid your blonde, the faster you'll need to return to the salon.
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.
Colorist Kim Vo says to "apply [dye] to the roots first and then ends," and to avoid applying the color all at once. If you're covering white hair, colorist Emily Mott advises just coloring your new growth and avoiding the ends altogether to keep things from looking "over-processed."
When it comes to salon treatments, the best professional hair color line is Wella Illumina Permanent Creme Hair Color. Available in 36 shades, the colorist-recommended formula is gentle, versatile, and leaves hair oh-so-shiny.
