Your hair may look fried and damaged

• The chemicals in the dye may damage your hair.
• The heat of the dryer, flatiron, and curling iron can also damage your hair.

If you’ve ever had your hair dyed at a salon, you’re probably familiar with the process of getting a test patch done before the actual dyeing takes place. If that’s not something they do at home, it might be worth asking if they can recommend a product that will allow you to test out the color beforehand. While it’s true that most people don’t want their natural hair color, there are many who want (and can afford) their hair to be as close to their natural roots as possible. If yours falls into this category, then it’s super important that your new shade matches up perfectly with what’s under there!

It will likely not look even or smooth throughout all areas where you applied dye.

It can burn your scalp

Dyeing your hair at home can be risky, especially if you’re not careful. One of the most common dangers is an allergic reaction to the chemicals in your dye kit. A chemical burn occurs when a chemical comes into contact with skin or mucous membranes (like your mouth and eyes), causing irritation or inflammation. This type of burn usually heals within two weeks without treatment, but it can become severe if left untreated—and even lead to permanent damage.

If you suspect that you’ve gotten a chemical burn on your scalp, wash off any remaining dye immediately and see a doctor right away for evaluation and treatment options. You might need antibiotics or steroids to reduce swelling and pain; if the area has been exposed to chlorine from tap water or hydrogen peroxide from hair products, it may also require treatment with soothing aloe vera gel or tea bags soaked in milk until the burns heal completely.

You could have an allergic reaction

It’s also important to know that you could have an allergic reaction to the dye. You can do a patch test in order to see if you are allergic, but this does not work for everyone. If you do have an allergic reaction, it will likely be itchy and uncomfortable. You should see a doctor if your symptoms get worse or don’t go away after several days.

It’s better to have a professional do it.

I know that many of you will want to save money by doing your own hair dye at home. But, it’s always better to have a professional do it.

Here are some things to look for in a good salon:

• They should have all the necessary equipment, including an assortment of colors and chemicals. If not, they may not be equipped to handle a minor accident like this one that happened to me when I dyed my own hair: “I used bleach on my hair instead of dye and now I’ve got orange stripes.”
• The salon should also have someone on staff who can answer questions about what products are safe for your particular type of hair (whether yours is thick or thin). If you’re unsure about which products are best for you, don’t hesitate to ask! A good stylist will give you tips based on their experience with many different types of clients over time; they’ll also recommend certain steps in order for you get better results from future dye jobs – such as how often (or how rarely) should go back into the salon each month so that there aren’t noticeable roots after two weeks!
