Don’t shampoo your hair for at least 48 hours after coloring.

After the first 48 hours, you should go ahead and wash your hair with a gentle shampoo. But don’t use conditioner—and definitely don’t use heat tools like blow dryers or flat-irons.

This is because color-treated hair has been stripped of natural oils that protect it from damage and moisture loss, so exposing it to any kind of friction or heat can cause breakage. And if there’s one thing we all know about breakage, it’s that no one wants that!

Use a color-protecting shampoo and conditioner.

Color-treated hair can benefit from using a shampoo and conditioner that protects hair color. You can buy these types of products at the drugstore, but you may not find the one you want there, so it’s best to look online. There are many brands out there that offer color-protecting shampoos and conditions, some even specifically for blonde or brunette hair. The ingredients you’re looking for are sodium pyrithione zinc or copper, amodimethicone (also known as cyclomethicone), quaternium-18 bentonite or polyquaternium 38 (also known as polyquaternium 10), dimethicone copolyol/cocamidopropyl betaine, cetrimonium chloride laureth-3 phosphate sodium sulfate cocamidopropyl betaine cocamide DEA PEG-120 methyl glucose dioleate polysorbate 20 peg 30 peg 40 peg 60 peg 80 PEG 100 olefin sulfonate parabens phenoxyethanol triethanolamine bht benzyl alcohol ethylene glycol denatured ethanol fragrance citric acid monohydrate.

Avoid dyes, styling products, and heat.

• Avoid sulfates. Sulfates are a common ingredient in hair products and can render your color less vibrant and more prone to fading. Steer clear of products with sulfate, especially those that contain sodium laureth sulfate (SLES), sodium lauryl sulfate (SLS), ammonium laureth sulfate, or ammonium lauryl sulfate on their list of ingredients. If you’re unsure whether a product contains SLES or SLS, check the packaging; if it doesn’t say “sodium,” chances are good that it’s safe to use on your colored locks!
• Avoid heat styling tools like flat irons and blow dryers, which will cause damage to your hair and make it brittle over time—and this damage shows up as dullness because the cuticle is compromised under extreme temperatures.* Also avoid any chemical treatments such as straightening or perming.* Make sure you don’t use too much styling product either—too much product will weigh down your strands and make them look greasy after only one day.* Finally: no more dye! If you’ve dyed your hair recently (or have plans for another color job soon), avoid dying it again until after two weeks have passed by making sure no dye touches those freshly dyed roots.*

Keep your hair hydrated with air conditioning.

One of the best ways to keep your hair color looking fresh is by protecting it from damage. Air conditioning can help with this because it keeps the air in your house cool and dry, which means that you won’t have to worry about humidity causing wetness or dampness on those days when you’re stuck inside. If you’re lucky enough to live in a place where there’s not much humidity, then being able to turn on your AC will be a lifesaver for keeping your hair shiny and healthy-looking!

Take care on day one.

If you want your hair color to last longer than two weeks (or if you just want a less expensive trip to the salon), here’s what you should avoid doing:

• Avoid going to the gym. Sweating, especially in places where there is no air conditioning, will cause your scalp to produce oil and sebum which can make your hair look dull or dry.
• Avoid swimming in chlorinated pools or oceans; it’s bad for both the body and the hair follicles!
• Never leave home without applying sunscreen on any exposed parts of your body like hands and face because exposure to ultraviolet rays can damage both skin cells as well as pigment found within hair follicles causing premature fading of color as well as breakage due to breakage caused by environmental stressors such as windy days when walking around town shopping for groceries at local farmers market nearby supermarket stores with plenty stock available so don’t worry about running out before next week arrives again!

Only apply color to unwashed or second-day hair.

The best time to apply color is when you haven’t washed your hair in at least two days. This gives the color a chance to settle into the hair and not simply wash away with your next shampoo.

• If you have oily or greasy hair, wait until that gets under control before applying the dye (or at least make sure to use a dry shampoo).
• The more porous your hair is, the faster it will absorb pigment and hold on to it—which means that freshly-washed, newly-colored locks may not be able to take on as much pigment as they could otherwise.

Don’t wash your hair in hot water for the first five days after coloring.

One of the best ways to make your hair color last is to use warm or cool water instead of hot when washing. Do not wash your hair for the first five days after coloring it. Hot water can cause the color to fade faster, and it can also dry out your hair. If you must wash with hot water, rinse with cold afterward.

Only wash your hair twice a week maximum.

The best way to keep your hair color from fading is to wash it less often. That’s right, you heard me! The more you shampoo and condition your hair, the faster that unwanted yellow tinge will start showing up in your strands. The color molecules can only hold onto their vibrancy for so long before they break down and need replacing with new ones—so if you’re constantly washing away these oils by over-conditioning or using harsh shampoos, then the natural color pigment may never have enough time to fully develop into its full potential before fading away prematurely.

Washing too much can also strip your scalp of its natural oils which will cause dandruff as well as make it vulnerable to other irritants like sun damage or windburns (which further accelerates fading). If this happens to be an issue for you, try switching out one of those two days’ worth of shampooing with a dry shampoo application instead! This will keep those pesky hairs clean without stripping them completely dry.

Make hair color last longer by taking care of your hair in the days and weeks after color treatment.

If you want to make your hair color last longer than two weeks, then you have to take care of your hair in the days and weeks after color treatment. Here are some tips for doing just that:

• Use a deep conditioning treatment for intense hydration and shine every three days or so. This can also help protect against damage caused by heat styling tools like curling irons or straighteners.
• Use a hair mask weekly (or bi-weekly). A good one contains ingredients like coconut oil, jojoba oil, argan oil and avocado oil to deeply hydrate the strands while protecting them from drying out too quickly when exposed to heat styling tools such as blow dryers and flat irons.
• Wear a shower cap while washing your hair if possible – this will keep water out of your ears/under ears where it can sometimes seep into sensitive skin areas causing irritation/pain! It’ll also help keep those pesky rinses from running down onto cheeks & necks where they could cause splotches later on if not dried off quickly enough before applying makeup products such as foundation etc..
