Why Do Salons Wash Your Hair After Coloring

Have you ever wondered why hair salons wash your hair after coloring it? Although washing your hair after coloring may seem like an unnecessary effort, there is research to support this practice. Understanding why some procedures are done in a salon can help you maintain the health and vibrancy of your hair, ensuring that your new color lasts as long as possible.

This article will explain why hairdressers wash your hair after coloring it and some tips on how to take care of colored hair.

The Science Behind Hair Coloring

Hair dye is made up of a variety of chemicals that work together to change the pigmentation of your hair. The most important component is known as “oxidative dyes,” which interact with hair protein to change the color of your hair. Ammonia, which is typically present in dyes, aids in opening the hair’s cuticle so that color may penetrate the hair strands.

In addition to the different conditioning agents that protect your hair from damage during coloring, hair dyes also often contain hydrogen peroxide, which is used to activate the oxidative dyes.

These chemicals are harsh on your hair. Therefore, it’s important to take care of your hair both before and after coloring. Some color molecules stay on the surface of your hair shaft after the dye has been applied and rinsed away. If this residue isn’t removed, it could cause fading or discoloration over time, which could be harmful. To prevent this problem, hair salons always do a wash and conditioner to remove any pigment molecules that may still be on your scalp and hair. This helps to make sure that all dye is thoroughly removed from your hair, preventing further harm.

After coloring, use gentle shampoo and conditioner, and try to limit the use of heated hair styling tools. To keep your hair strong and healthy, you might also consider applying hair masks or a deep conditioning treatment once a week.

1. Use Dry Shampoo

2. Maintain a healthy diet.

Your diet greatly affects the condition and appearance of your hair. A good diet provides the energy that promotes hair growth and luster. Iron- and protein-rich foods nourish your scalp and hair by helping to form keratin, a protein that fortifies your hair, enhances its texture, and promotes hair growth.

Your choice of shampoo is a key factor in preventing your hair color from fading. Use a shampoo made specifically for hair with color treatments when you do wash your hair.

After the color treatment, your hair is vulnerable to chemicals and heat. Therefore, it is advised to refrain from using style products on your hair for a few days, such as hairdryers, flat irons, and curling irons. Apply an anti-heat spray to your hair to protect it if you must use these tools to style your hair. The heat can make your hair appear duller and could lead to frizzy, dry, and damaged hair in the end.

5. Use Conditioners 

To prevent dryness, dry hair, and long-term damage after coloring your hair, it’s crucial to keep your hair healthy and hydrated. An excellent conditioner will help with this. However, conditioners also help to detangle hair and provide your locks with the nutrients they need to protect against damaging environmental factors.

Use a thick conditioner at least twice or three times a week to give your hair the moisture it needs.
