Use sulfate-free products.

If you want to make sure that your dyed hair stays beautiful, try a sulfate-free shampoo. Sulfates are what give traditional shampoos their foaming properties, but they also strip your hair of its natural oils and color. Sulfate-free shampoos don’t foam up as much as regular shampoos, but they’re gentler on your strands and tend to be more moisturizing. They’re also often less drying than regular shampoos—a real godsend if you have fine or otherwise delicate hair!

Don’t wash your hair more than two or three times per week.

The first thing to remember when washing your purple hair is that you shouldn’t wash it too often. If you wash your hair too much, the color will fade and your hair will start to feel dry. You absolutely should not wash your hair every day—this can strip natural oils from the scalp and cause damage over time.

Washing once or twice per week is a good rule of thumb (the science-y term for this is “sebum production”). Sebum production refers to how often your scalp produces oil as part of its normal function–it’s different for everyone! For example, some people produce more sebum than others; if this describes you then washing less frequently might be beneficial for maintaining healthy colored locks like mine! There are also ways we can change our shampoo routine so that we can get away with washing less frequently than usual–like using sulfate free shampoos which don’t strip as much moisture from our strands!

Use the right water temperature.

• Use warm water to wash your hair. Warm water will open the cuticle and allow for better penetration of shampoo and conditioner.
• Use cold water to rinse your hair. Cold water closes the cuticle, which helps seal in color. This is an important step when it comes to maintaining your purple hues!

Use a silk sleep cap or pillowcase to prevent hair from tangling when you sleep.

• Use a silk sleep cap or pillowcase to prevent hair from tangling when you sleep.
• Silk is a natural fiber that prevents hair from snagging and breaking, so it’s better for keeping your hair healthy. It’s also good for your skin and will give you fewer breakouts than cotton. The other benefit of using silk is that it feels very soft against the skin, so it won’t irritate sensitive areas like the face or neck area where some people have sensitive skin because they’ve got acne or rosacea.

Wash only once with shampoo and conditioner.

• Use the right shampoo. Always be sure to use a color-safe shampoo, which is formulated specifically for dyed hair. This will help prevent fading and other damage that can happen when using regular shampoos on colored hair.
• Only use conditioner on the ends of your hair, not on your scalp. You don’t want to rub conditioner into or near your roots because this could make it appear greasy and cause worse damage in the long run.
• A wide-tooth comb is best for removing tangles before washing, but don’t brush wet locks as they can become damaged if pulled too much while they’re still damp and weak from being submerged in water!
• Don’t wash every day; only do so once per week–and definitely never use hot water! You’ll be able to see how much better your hair looks after just one or two washes following these rules!

Rinse your hair with cool water at the end of your shower.

At the end of your shower, rinse your hair with cold water. The cool temperature helps to close hair follicles and prevent frizz, which can cause broken strands to fall out. It also helps set the color in your hair while reducing dandruff and scalp irritation.

Add a purple shampoo to your routine.

When choosing a purple shampoo, it’s important to look for one that is designed specifically for your hair color. If you have gray hairs, you may notice that they will become lighter in tone after using this product. This can be helpful if you want some extra lightness to your hair—but if not, try using the product less often or waiting until after you’ve colored your hair again before using it.

If your dyed locks are feeling dry or brittle (or even just need some extra moisture), try adding a leave-in conditioner or volumizing spray into the mix of products you use on them before washing them off with shampoo and conditioner.

Deep condition your hair once a week with a product that’s designed for purple-gray hair.

Deep conditioning is a great way to restore moisture and elasticity to your hair. It also helps to prevent dryness, breakage, and dullness (which can sometimes happen with dyed hair). To get the most out of deep conditioning treatments, it’s best to do them once per week. You’ll notice an immediate difference in how soft and shiny your hair looks after each treatment!

Apply leave-in conditioner before swimming.

You can also use other products like a swim cap or hair spray to protect your hair from the sun and chlorine. However, if you want to get the most out of your leave-in conditioner, apply it before swimming instead of after. This way it has time to work into the strands and protect them from salt water as well, which causes breakage and dullness.

Protect the color when you’re in the sun.

• Use a leave-in conditioner or hair serum to protect your color from the sun.
• Avoid styling your hair with heat, as it can cause damage and fade the color.
• Get a hat when you’re outside for long periods of time, especially if you’re in direct sunlight for extended periods of time. Sunscreen is also an option if you’re worried about damaging your hair by getting out in the sun more often than needed!
• Wear a swim cap when swimming! This will prevent chlorine from seeping into your hair and fading the dye over time (and it’s just better for everyone that way). If possible, use a shampoo designed specifically for swimmers so that there are no adverse effects on the integrity of their natural oils or other products they might put on afterward (for example: conditioners). For extra protection try using an oil beforehand so that it doesn’t get washed away when washing out after each session; this should help keep things healthy between sessions too!

Keeping your dyed purple hair is possible, but it takes some care!

Keeping your dyed purple hair is possible, but it takes some care! Using the right products and tools as well as keeping a consistent temperature is key to making sure that you’re not damaging your hair.

On top of using the right products, using them at the right temperature can be really important. The water should never get too hot because this can cause damage to the dye job and lead to more frequent dyes needed in order for it to cover your entire head.
