Understanding the pH level (acid-base balance) is key to achieving professional results when performing straightening, botox treatments, and daily hair care. At Beauty Brazil, we categorize shampoos into three main types. Let's explore the purpose of each.
1. Alkaline Shampoos (pH 7.5 – 9.0)
These products have a high pH level and provide intensive effects on the hair structure.
Why use them? The alkaline environment effectively removes all dirt and styling residues. The main goal of this shampoo is to “open” the keratin cuticles.
Who are they for? Used exclusively before professional treatments on natural hair that has not undergone chemical processing.
Important: If you don’t use an alkaline shampoo before a treatment on healthy hair, the product may not properly adhere, and you won’t achieve the desired effect.
2. Neutral Shampoos (pH 7.0)
Shampoos with a neutral balance are the “golden mean” for preparing delicate hair.
Why use them? Provide quality cleansing while being gentler than alkaline formulas.
Who are they for? Ideal for preparing hair with light damage (such as colored hair) for keratin straightening or botox treatments.
3. Acidic Shampoos (pH 4.0 – 6.5)
This category includes products with a low pH designed for gentle cleansing and maintaining hair structure.
pH 5.5 (Balance): A shampoo for daily use. Suitable for normal hair care and preparing heavily damaged or repeatedly lightened hair for treatments.
pH 4.0 – 4.5 (Extra-Acidic): Used immediately after aggressive procedures (coloring, keratin, botox).
Effect: These shampoos “seal” the cuticle, locking in beneficial ingredients and pigment inside the hair. They work very gently, helping preserve hair quality and extend salon treatment results.
Conclusion: Choosing the right pH shampoo is 50% of your treatment’s success. Choose your products wisely with Beauty Brazil!
