Should I use shampoo after dyeing your hair?
A few years ago, the "poo-free movement" gained popularity, advocating against shampoo due to its chemical impacts on the environment and health. However, the abundance of shampoos on the market indicates their necessity. Throughout the day, our scalp and hair accumulate dirt, vehicle exhaust, rainwater, and sweat. Without shampoo, these impurities can't be effectively removed, leading to excessive oil secretion and scalp issues. Thus, using shampoo before and after dyeing is essential, as its surfactants help wash away dirt and oil.
The answer is: yes. Hair color fades primarily because the cuticles open during washing, which removes both dirt and hair color. Regular shampoos are mildly alkaline and open the cuticles more to cleanse the scalp effectively, causing more pigment loss. Bleached hair has more damaged cuticles, leading to increased color loss after dyeing. Since you can't wash hair with just water and regular shampoos cause color loss, you need to understand the use of "color-depositing, toning, and color-protecting shampoos" to prevent your expensive hair color from fading too quickly.
Specialized shampoos for bleached and dyed Hair: Color-Protecting Shampoo, Toning Shampoo, Color-Depositing Shampoo, How do I choose?
Understand at a glance: Color-Depositing, Color-Protecting, or Toning Shampoo
Color-depositing, toning, and color-protecting shampoos each have their own benefits. Choose the right product based on your needs; you don't need to use all three. Decide based on whether you need to "deposit color" or "toning yellow pigments" after fading.
For instance, if you simply dye your hair and the color is similar to your natural hair color, your main need is to "slow down the fading process." You can use a color-protecting shampoo without adding more color. For lighter dyed hair or bleached hair, where the fading is more noticeable, a color-depositing product is necessary.
After one to two months, if your hair starts showing yellow pigments due to fading, use a toning shampoo. If you want a softer color effect, mix the MCG Toning Shampoo - White with your color-depositing shampoo for a matte finish.
Dye hair washing routine: Can I use Color-Protecting, Toning Shampoos, and Color-Depositing Shampoos daily?
Color-Protecting Shampoo
Regardless of whether you have simply dyed your hair or undergone bleaching, it is recommended to start using color-protecting shampoo immediately after dyeing. As mentioned, regular shampoos open the cuticles during washing, causing color loss. Color-protecting shampoos contain antioxidants that effectively slow down fading. They can be used daily, but it's advisable to wash less frequently or use a regular shampoo first if the scalp is very oily, followed by the color-protecting shampoo. Alternatively, you can alternate between regular and color-protecting shampoos.
Color-Depositing Shampoo
There are two times to start using color-depositing shampoo. For those who prefer natural fading, use it when the color is almost gone. For those who want to maintain vibrant color, use it right after dyeing. One use lasts for 2-3 washes, so you can alternate with color-protecting or regular shampoos. If you use color-depositing shampoo today, use regular or color-protecting shampoo next time. Since color-depositing shampoos are mildly acidic and less cleansing, it's recommended to use a regular shampoo first, followed by the color-depositing shampoo.
Toning Shampoo
For platinum-blonde bleached hair or overly saturated dyed hair, use a toning shampoo after dyeing to achieve a lighter, more translucent effect when you wash your hair.
Other ways to make hair color last longer
In addition to using color-depositing, color-protecting, and toning shampoos, paying attention to the following 4 points can also help maintain your hair color longer!
1. Wait 2 days before washing hair after dyeing
After dyeing your hair, it's recommended to wait two days before washing it. Newly colored hair needs time to bond with oxygen in the air, which stabilizes the pigment particles and helps the color set beautifully. Additionally, your hair is typically washed at least twice on the day of dyeing, so waiting a few days before washing again prevents over-cleaning, which can disrupt the oil and moisture balance, cause dryness and itching, and reduce color retention.
2. Avoid high water temperatures
Hot water can cause hair cuticles to over-expand, accelerating the loss of dye molecules and irritating the scalp.
3. Apply hair oil before using heat tools
Heat tools include hairdryers, flat irons, and curling irons. Many people have seen the comparison where a flower petal without hair oil burns when clamped with a flat iron, while the one with hair oil remains intact. Hair oil helps prevent heat damage and also assists in closing the hair cuticles, which slows down pigment loss.
4. Protect your head from sun exposure
Prolonged UV exposure accelerates hair oxidation, which causes color fading, especially for bleached hair. After a beach trip, you may notice your hair feels dry and fades due to the salt in seawater. To prevent this, protect your head from the sun, just as you would your skin. The head is the most exposed to UV rays, so it's crucial to use sun protection for your hair during sunny days.
