Introduction to coloring and shampooing

What is hair coloring?

Visit hair coloring is a cosmetic process that allows you to change the natural color of your hair. Whether to cover gray hair, keep up with the latest fashion trends or simply express your personality, coloring can transform your appearance. However, it's essential to understand its specifics to get the most out of it.

Types of hair colorants

• Permanent dyes : They penetrate the hair fiber and last until the hair grows out or the color is changed. Often used for radical color changes, their use requires rigorous maintenance.
• Semi-permanent colorants : These colorants add pigment without altering the hair's natural structure. Their effect generally fades after 20 to 30 shampoos.
• Temporary colorants : Applied to the surface, they disappear after one or two shampoos. Ideal for a one-day makeover or to try out a new color without commitment.

Importance of shampoo

Shampoo plays a crucial role in maintaining the health and appearance of color-treated hair. Choosing the right product and respecting the right timing is essential for preserving color intensity and longevity.

How does shampoo affect color-treated hair?

• Pigment deterioration : Using the wrong shampoo or shampooing too frequently can cause pigments to fade, shortening the life of your color.
• Scalp health : A healthy scalp promotes color retention. Aggressive shampooing can not only impact color, but also cause irritation.
• Hydration management : Color-treated hair requires special moisturizing. The wrong shampoo can damage hair health by stripping it of its natural oils.

Optimum timing for shampooing after coloring

Recommended waiting time after coloring

After color application, it's essential to know when to shampoo for the first time. It's generally advisable to wait at least 48 to 72 hours before washing your freshly-colored hair. This waiting period plays a crucial role in fixing the pigments and ensuring that the color doesn't fade quickly.

Reason for waiting period

• Pigment stabilization : The coloring process opens the hair cuticle to allow pigments to penetrate. Waiting a few days after coloring gives the cuticles time to close, securing the pigments inside and increasing the color's durability.
• Water avoidance: Water, especially chlorinated water, can cause premature discoloration. The longer the time between coloring and the first shampoo, the greater the chance for pigments to set effectively.

Consequences of immediate shampooing

It can be tempting to wash your hair immediately after coloring, especially to get rid of the chemical smell or any excess dye. However, this can have detrimental effects on the color and health of your hair.

Impact on hair color and health

• Early color loss : Premature washing can remove a significant portion of the applied pigments, leaving your hair dull and compromising the intensity of your chosen color.
• Increased fragility : Freshly-colored hair is more vulnerable to external damage. Premature shampooing can weaken hair fibers, making hair brittle and less resistant.
• Dewatering : The chemicals in colorants can already tend to dry out hair. Shampooing too quickly after coloring can exacerbate this phenomenon, robbing hair of its natural moisture and leading to dry ends.

Tips for maintaining hair color after shampooing

Choosing the right shampoo

Selecting the right shampoo is crucial to prolonging the life of your color. Not all shampoos are created equal, and some can even be detrimental to color stability. So it's essential to choose a product specially formulated for color-treated hair.

What to look for in a shampoo for color-treated hair

• Sulfate-free formula: Sulfates are powerful cleansing agents that can discolor hair. Opt for a sulfate-free formula for maximum gentleness that helps preserve pigment brilliance.
• Enriched hydration : Look for ingredients that offer extra hydration, such as argan oil, keratin or glycerine. These ingredients nourish hair fibers to keep them supple.
• UV protection : The sun's rays can fade colors. A shampoo with UV protection helps preserve the intensity of your color under the sun.
• pH balanced : A pH-balanced product is less aggressive on color-treated hair, allowing cuticles to stay closed and pigments to stay locked in longer.

Care protocols for color-treated hair

Adopting a specific care routine for color-treated hair maximizes the durability and fullness of your color. A well-designed, preventive approach helps avoid premature color fading.

Washing and packaging techniques

• Washing intervals : Washing your hair too frequently approves of rapid color fading. Try to reduce the frequency of your shampoos to two or three times a week if possible.
• Use lukewarm water : Hot water can open cuticles, causing pigment leakage. Use lukewarm water for washing and rinse with cold water to seal cuticles.
• Weekly deep conditioner : A deep conditioning treatment once a week strengthens hair structure and keeps it moisturized. This helps protect color against external aggressions.
• Natural drying : Reduce the use of heated tools such as hair dryers or straightening irons. If you must use them, apply a thermal protector and choose a low heat setting.
• Soft combing : Use a wide-tooth comb to detangle your hair when it's damp. This minimizes breakage and keeps hair fiber structure intact.

Myths and truths about coloring and shampooing

Common myths

Clarifying myths

Hair color is often surrounded by myths that influence the way people care for their color-treated hair. Understanding what's true and what's not can help you optimize the longevity of your color.

• Myth: Using a purple shampoo only works for color-treated blond hair.
• Truth: While violet shampoos are known to neutralize unwanted yellow tones in blonde hair, they can also help maintain cool undertones in other lighter or ashy colors.
• Myth: The more shampoo lathers, the better it cleans and preserves color.
• Truth: Lather is not an indicator of cleanliness or color protection. Sulfate-free shampoos, which foam less, are often gentler and more beneficial for color-treated hair.
• Myth: Natural coloring such as henna requires no special care after application.
• Truth: Although henna is natural, it also fades over time and requires appropriate care to maintain its radiance, as with any other hair color.

Verified facts

Research supporting the facts about hair coloring

Scientific studies confirm several hair color nuances that are often overlooked.

• The pH of hair care products: A shampoo with a pH around 4.5 to 5.5 can help seal the hair cuticle, which is essential for keeping pigments in and ensuring long-lasting color.
• Effects of UV radiation: Color-treated hair is more susceptible to UV damage, which can lead to rapid fading. The use of products containing UV protectors has proven effective in protecting against lightening.
• The importance of hydration : Bleached hair requires more moisture due to increased porosity after coloring. Moisturizing agents like glycerine and coconut oil have been shown to help retain moisture and prolong color vibrancy.
