The book "Development of Hair Conditioning Shampoo with Glycolic Acid" offers a comprehensive analysis of the properties and benefits of hair care products containing glycolic acid. It highlights the effectiveness of conditioning shampoos that not only improve hair structure but also enhance shine and smoothness. The authors examine the ability of these products to protect, moisturize, and strengthen hair, thereby preventing damage and breakage in both healthy and colored hair. The stability of the product is also discussed, noting that there are no changes in color, scent, or pH over a period of one month. These findings are particularly valuable for professionals in the hair care industry and for students involved in the development and application of cosmetic products.
