How Often Can You Dye Your Hair Without Damaging It

As the flavour changes and fall approaches, nosotros've received many questions about changing hair colour. How often y'all tin make that change – or maintain 1 – is a slap-up question to ask when concerned with your color treated pilus health.

Today'due south innovations in hair dye applied science mean that altering or enhancing your natural hair hues needn't exist inherently dissentious, just how often information technology'southward done depends on how it'due south washed – and how you intendance for it between salon hair coloring appointments with the correct hair wash and maintenance. The practiced news is that there's no reason why dyed hair can't stay in vivid shape.

one THE Hair Colour METHODS

How frequently tin can you dye your hair safely? It depends primarily on which method of pilus color yous and your colorist cull: permanent pilus colour, semi-permanent hair colour, or demi-permanent hair color. The long and short of permanent vs semi vs demi permanent is this:

Permanent hair color has the greatest potential for pilus damage due to the chemistry involved and should be done most cautiously. Ammonia and hydrogen peroxide combine to open up the hair'southward cuticle to achieve the internal structure and make a color modify. Permanent hair colour can either lighten or darken and can last up to viii weeks, although it may require touching upwards at the roots as your natural color grows in.

Permanent color is the best way to reach full coverage of greyness hair, and information technology's more a matter of growing it out rather than washing it out. It may be used in any coloring process or technique, including single procedure (bleach-only), double process, highlights, lowlights, and balayage.

If a lot of bleach is involved to considerably lighten your hair, referred to equally "lifting," your pilus may be very porous, which ways it is prone to moisture loss, fragile, and susceptible to environmental discolorants such as smoke or the cosmetic colorants other hair products may contain. So how do you accept intendance of bleached hair?

In this case, count on waiting at least 4 weeks before y'all repeat the coloring process to spare your hair from potential harm. The less frequent, the better. Of class, if your pilus is very curt and you cut it frequently, hair damage is less of a business organization. There are still options for how to become rid of brassy hair if your blonde is turning orangey between hair appointments.

Re-dying the entire length of your hair tin be washed safely nearly every eight weeks, simply if you simply want to make a tonal change – warm information technology upwards or cool it down – there are less permanent and non-damaging – options.

The frequency of root touch-ups depends on how long you can tolerate seeing your re-growth, and since they are performed on "virgin" hair, frequency is at your discretion. Go on in mind that the average growth charge per unit is a half an inch every month. Re-dying the entire length of your hair can be washed safely almost every viii weeks, but if you simply want to make a tonal alter – warm it up or cool it down – there are less permanent – and not-damaging – options such as glazes or toners in the semi-permanent color category (more below).

Demi-permanent hair color is ammonia-free but requires a small corporeality of peroxide to slightly elevator the outer hair cuticle so that the pigment can take concur without lightening your natural color. As long every bit the hair cuticle is properly restored to its naturally flat and closed position – and you've followed the intendance protocol (more on that below) – you lot should be able to safely re-color your pilus every bit often every few weeks.

For colorist Julia Elena, how frequently you can safely use demi-permanent color depends on your hue, even if color is not applied overall: "It is only potentially damaging to blondes achieved with abiding bleaching. I recommend waiting up to 3 weeks if necessary for touch-ups, but otherwise, I recommend they let their hair 'breathe' until the next full service. Otherwise, demi-permanent color isn't harsh on brunettes and reds, and since bleach is rarely involved, they can come in often without business concern – though it'southward non usually necessary."

Stylist and colorist Jennifer Covington-Bowers adds that it depends on what demi-permanent color is used for. "If it's simply used to blend grays, I say 4 weeks is a skillful interval. I also use it to give shine and dimension by using information technology every 6 to 7 weeks, or just about the boilerplate fourth dimension between haircut appointments when I will do both. If I'k using it to right color, it can be washed sooner than 4 weeks afterward the initial service, but I pay extra attention to keeping the hair healthy throughout the process."

Semi-permanent color can exist safely used as often as your wants and whims modify – perfect for a weekend mode fling. This depression-maintenance and short-term pick is only a stain or toner that is deposited on the surface and can be removed in as little as i washing if you use an aggressive cleanser, such as a clarifying shampoo, which by itself can exist more damaging than the pilus dye volition e'er be.

2 COLOR MAINTENANCE AND HAIR HEALTH

Since permanent colour is a chemical process that occurs inside the hair cobweb, it tin can break a number of the structural bonds (disulfides) that hold the protein strands together and tin can exit your color treated hair breakable, porous, and more damage-prone. The more often you color your hair, the more protein y'all lose, and it can become challenging to comb, manner, maintain, and the likelihood of split ends increases.

A couple of tips for dyed hair to stay healthy:

• Selection a color-safe washing and conditioning option.
Wash and status with products designed to do the job safely and gently. New Wash is color-treated hair's BFF because information technology contains no damaging detergents that strip your pilus of its colour. It also conditions while information technology cleanses, and helps you preserve your natural oils that hair struggles to be healthy without.

• E'er use a rut protectant.
Adding thermal insult to chemical injury is a recipe for hair disaster. If y'all're in the habit of accident-drying or using a curling or straightening iron, please, pretty please, apply a product that insulates your strands from the heat and continue information technology from drying out or worse, getting scorched. Dressed Upwards applied to damp hair before the idea of a blow-dryer enters your head is the way to become, as it also adds a soft hold, and supplements some of the moisture y'all're certain to lose.

• Effort moisturizing oils.
Pure oils can be effective frizz-fighting salves for dry pilus. Covington-Bowers recommends olive oil lonely or every bit a base for almond, amla, black castor, or coconut oil. All accept natural properties that penetrate strands to help repair and prevent additional impairment. "But make sure you lot aren't allergic first by dabbing a tiny amount on your pare and exist watchful for a reaction like redness or itching," she cautions. "In fact, before trying whatever new product, test it on a pocket-sized section of pilus starting time and watch how it responds."

So go forth and color, but keep in mind that all that fun that blondes are purported to have can be spoiled with too much bleach. And so stay safe and listen to your colorist: your hair health – and their hard work are always their first concerns.
