Keune Keratin Straightening Rebonding System is a professional, two-step hair treatment designed to permanently straighten frizzy, curly, or wavy hair. The product you're asking about, "Keune Keratine Straight Normal X2," refers to the "Normal" formula of this system, which is intended for fine or normal hair types. The "X2" indicates that the package contains both steps of the treatment: a straightening cream and a neutralizing cream.

Here's a breakdown of the key features and information about this product:

Permanent Straightening: This is not a temporary keratin treatment. It is a chemical rebonding system that works by breaking and reforming the hair's disulfide bonds to permanently alter its structure, resulting in straight hair. The results are said to last for several months, with touch-ups needed as the new hair grows in.

Two-Step Process: The system involves two main components:

Straightening Cream: This cream breaks the bonds in the hair to allow it to be reshaped.

Neutralizing Cream: This cream rebalances the hair and locks the new, straight shape in place.

Formaldehyde-Free: Keune emphasizes that this system is 100% formaldehyde-free, which is a key safety feature that distinguishes it from some other straightening treatments.

Enriched with Keratin and Silk Proteins: The formula includes a "Kera-glide complex" with keratin and silk proteins, which are intended to provide conditioning, nourishment, and protection to the hair during the chemical process.

"Normal" Formula: This specific version is for hair that is described as "fine to resistant" or "naturally strong, resistant to very resistant." Keune also offers a "Strong" version for very coarse or resistant hair.

Professional Use: The Keune Keratin Straightening Rebonding System is intended for professional use in a salon setting. The application process requires careful steps and the use of a straightening iron to achieve the desired results. It's crucial to follow the instructions precisely to avoid damage to the hair.

Important Considerations:

Hair Type: It's essential to select the correct formula (Normal or Strong) for your hair type to prevent damage.

Pre-treatment: Keune recommends a pre-treatment, such as a protein spray, to protect the hair and balance its porosity before the straightening cream is applied.

Maintenance: To maintain the results and keep hair healthy, it's recommended to use a good hair care routine with products designed for chemically treated hair.

Color-treated hair: The "Normal" formula can be used on color-treated hair if it's in good condition, but it should not be used on bleached, highlighted, or severely damaged hair. A waiting period of at least two weeks after a color service is also recommended.
