Clairol Colour Strong Permanent Hair Dye - 4.46 Intense Dark Red

Yes, absolutely. A 48-hour skin allergy test is crucial before every application of hair dye, even if you've used the product before. Allergic reactions can develop suddenly, so this step is vital for your safety.

As a permanent hair dye, the color itself will not wash out. However, the vibrancy may gradually fade over time, and new hair growth will appear at the roots. Expect the color to remain vibrant for several weeks before a touch-up is typically needed.

Yes, this permanent dye can be used on previously colored hair. However, always perform a strand test first to see how the 'Intense Dark Red' shade will interact with your existing color and to ensure the desired result.

The AHA Bonding Treatment is a post-coloring conditioner enriched with Alpha Hydroxy Acids. It's important because it acts like a 'top coat' to seal in your new color, making it last longer and appear more vibrant. It also reinforces the hair's internal structure, contributing to stronger, healthier-looking hair after coloring.

Most permanent hair dyes, including this one, are typically used for root touch-ups every 4-6 weeks, depending on hair growth. For full head applications, avoid coloring more frequently than necessary to maintain hair health.

While the color is set after rinsing and treatment, freshly colored intense red hair can sometimes transfer a small amount of color, especially when wet. Use an old towel on your pillow for the first night or two, and be mindful of wet hair coming into contact with light-colored fabrics.

No, 'Zero Ammonia' means the product does not contain ammonia, a common alkaline agent in hair dyes. It is not natural or chemical-free, as it still uses other chemicals to achieve permanent hair coloring. The absence of ammonia generally makes for a less pungent smell and a potentially gentler experience.

Ensure the product was applied thoroughly to grey areas first, as they can be more resistant to color. Make sure the dye was left on for the full recommended processing time. For very resistant greys, some kits recommend slightly longer processing.

Uneven application is the most common cause. Ensure hair is fully saturated during application. Sectioning hair precisely and applying from roots to ends (or as directed for specific application types) helps achieve an even result. A strand test can help confirm proper processing time.

Immediately rinse the product from your hair and scalp if you experience severe irritation. This highlights the importance of the 48-hour skin allergy test before every application. If irritation persists, consult a medical professional. The ammonia-free formula helps reduce this risk, but individual reactions can still occur.

Ensure you used the provided AHA Bonding Treatment. This treatment is specifically designed to reinforce hair structure and improve its condition. For continued care, use moisturizing and color-safe shampoos/conditioners, and deep conditioning treatments regularly. Avoid excessive heat styling.
