When should I start dyeing my hair?

While there is no set time or age to start using these products, there are some important things to take note of, which depend on a variety of factors. Experts suggest keeping the below two considerations in mind when debating whether to dye your hair or not.

The first and most important of these is to dye your hair when you feel like it. You don't have to wait for grey hair to become an issue before making the decision.

Secondly, you should only start dying you hair when you are prepared to take care of your color. Once you start dying, you are going to need to continue for as long as you want a particular color. Time and money is required in order to keep your hair dyed indefinitely.

How often should I dye my hair?

There are a number of important factors to consider when deciding on how often to color your hair. An important one is how fast your hair grows. How damaged your hair is is another. The color you are going for is also important. You should prepare yourself to repeat the process every 3-4 weeks.

With that in mind, this isn't a hard and fast rule, and the cycle is determined by the aforementioned factors. Fast-growing hair needs more touch ups, as does color that is radically different from your natural one. If you have damaged hair, on the other hand, you will want to use hair dye less often.

How are hair dye products used?

The home hair dye market is massive, and most kits provide you with most of what you need to properly dye your hair form the comfort of your own home. Anyone who has been dying their hair for a while, however, will tell all newbies: the process is not as simple as it seems and takes some patience to perfect.

If you are unsure of how your skin is going to react, put a touch of it on your wrist before beginning to test for any allergies. If all is well, then you can start on your head. A good idea is to place a line of petroleum jelly along your hairline to avoid dying the surrounding skin. Thoroughly mix the dye components and then evenly spread it throughout your hair. Use the included brush to make sure it saturates root to tip.

After you've covered all your hair, massage it in to make sure everything is well covered. You can put a shower cap on while you wait for the dye to take effect. After that period has elapsed, thoroughly rinse your hair with water. Don't worry if it seems like the water contains a lot of dye, that is normal.

The second criteria is the duration of the dye. Hair dyes are grouped into categories based on how long they last. You need to know this before making a purchase. Knowing what you want in terms of duration is as important as the color it self.

A semi-permanent hair dye is, for instance, a great option if you're dying your hair for the first time.

You should also make sure you know what you're buying before making a purchase. Study the ingredient list and know what's in it. If you have preexisting skin issues, always talk to a doctor, and preferably a dermatologist before putting anything potentially harmful on your skin.

Type of hair

Everyone has different hair with different needs. Always keep in mind the kind of hair you have before purchasing anything. Dry and damaged hair requires different products, than fine and delicate hair.

If you have thin, dull hair, get a hair dye that improves volume and shine. Fine, delicate hair is more susceptible to damage. With that in mind, you should get something that doesn't have ammonia and does contain amino acids and moisturizers. Always get something that makes the most sense for your specific hair type.


Dying your hair is quite an involved process, and there are some thing you are going to need in order to do it right. Therefore, you should always make sure the out-of-the-box dye set you are buying includes the accessories that are necessary for doing it right.

These include things like dye mixing tools, combs, applicators, and spatulas. All of these combined make the dying process easier and more effective. Try and choose a product that comes with these essential hair dying tools.


In summation, hair dyes come with more features than you may originally have known about. It is no wonder they are an important part of so many peoples' cosmetic arsenal. If you can't stand your new greys, for instance, a good quality hair dye will help keep them at bay.
