Clairol Permanent Hair Dye ColorStrong 6.1 Light Ash Brown (Machu Picchu) — Ammonia-Free, AHA Bonding System, 100% Gray Coverage

Clairol ColorStrong 6.1 Light Ash Brown is a permanent, ammonia-free hair color kit that delivers full gray coverage and multidimensional ash-brown tone while reinforcing hair with an AHA-enriched bonding system.

This salon-inspired at-home kit combines color and structural care: a bonding primer, permanent color cream, activator, and a bonding treatment all formulated with AHA to help strengthen hair through the coloring process. The system aims to give even, reflective color without ammonia and is designed for those wanting long-lasting coverage and a cool, ash-toned finish named Machu Picchu.

How does the Color + Bonding system protect hair during coloring?

The kit uses a three-step approach—primer, color, and treatment—each containing AHA. The primer prepares the hair surface so dye can deposit evenly, the permanent color delivers pigment with support from bonding agents, and the final treatment seals the result while adding reinforcement to the hair fiber.

• Bonding Primer with AHA smooths and primes hair for even uptake
• Permanent Color Cream deposits multi-dimensional pigments and includes AHA
• Bonding Treatment seals color and helps restore tensile strength
• Complete kit includes gloves and clear instructions for at-home use

Will this product cover gray hair completely?

Yes — the formula is designed for 100% gray coverage when used according to the instructions. The permanent dye works to fully mask gray strands while producing a consistent ash-brown tone across the hair.

• Permanent formula targets and covers resistant gray
• Activator mixed with color cream ensures full pigment development
• Follow timing guidelines in the leaflet for optimal results
• Results vary with hair porosity and previous color history

Is the dye gentle on hair and scalp?

The product is formulated without ammonia, parabens, PPD/PTD and includes AHA in each step to support hair structure. While the absence of ammonia can reduce certain smells and harsh lifting action, color is still a chemical process—perform a patch test and follow safety directions to minimize risk of irritation.

• Zero ammonia reduces strong odor and aggressive lifting
• PPD/PTD-free and paraben-free formulation (avoid if PPD allergy exists)
• Includes instructions and gloves to limit scalp contact
• Patch test recommended before full application

What results and tone can I expect from shade Machu Picchu 6.1?

Shade 6.1 produces a light ash brown with cool, subdued highlights rather than warm copper or golden tones. Expect multidimensional depth and a refined ash cast that suits cool or neutral skin undertones when applied to natural or previously lightened hair.

• Light ash brown finish with cool undertones
• Multidimensional color with subtle reflections and depth
• Best on level 5–7 natural bases or on pre-lightened hair for precise ash effect
• Use the included bonding treatment to help maintain shine and integrity

Who is this for: Clairol ColorStrong 6.1 is aimed at at-home users who want permanent, ammonia-free coverage with a cool ash-brown result and who care about protecting hair structure during coloring. It's a good match for people seeking full gray coverage, multi-tonal depth, and a kit that supplies primer, color, and a finishing bond treatment. If you have a known sensitivity to PPD/PTD, do not use this product.
