Despite itching and dry hair from Kerastase, I think it's a top-notch product.
I had an allergic reaction with itchy skin and splotches, and my hair felt dry after using Kerastase shampoo, yet I believe it is a high-quality product that I would still recommend to others.
This is a review from Amazon.com about product:
KÉRASTASE Blond Absolute Lumiere Illuminating Shampoo for Lightened Highlighted and Damaged Hair, Nourishes and Illuminates, Adds Softness & Shine, Strengthens Damaged Hair with Hyaluronic Acid

I think it’s me not the product but I had an allergic type reaction, my skin felt itchy and splotches came up and my hair feels a bit dry following use. But it’s just my experience and would not discourage anyone from trying this because Kerastase is top notch product
Shampoo Basics & Tips
Understanding Allergic Reactions to Shampoo
An allergic reaction to shampoo, as described in the review with symptoms like itchy skin and splotches, occurs when the immune system responds to certain ingredients. Common culprits include fragrances, preservatives like parabens, or sulfates. These can cause contact dermatitis, leading to redness, itching, or hives. It's essential to patch-test new products before full use. If reactions persist, consult a dermatologist to identify specific allergens.
Causes of Hair Dryness After Shampoo Use
Hair dryness, mentioned as a side effect, often results from harsh cleansing agents like sulfates that strip natural oils. Shampoos with high alcohol content or inadequate moisturizers can exacerbate this. For individuals with sensitive scalps or dry hair types, choosing sulfate-free or hydrating formulas can help maintain moisture balance. Regular conditioning and limiting shampoo frequency can also prevent dryness.
About Kerastase Brand and Product Quality
Kerastase is a luxury hair care brand known for its high-quality, scientifically formulated products. It often uses premium ingredients tailored to specific hair needs, such as proteins and oils for repair. Despite potential individual reactions, as noted in the review, the brand's reputation for efficacy stems from rigorous testing and targeted solutions for issues like damage or thinning hair.
Common Shampoo Ingredients and Their Effects
Shampoos contain various ingredients that affect hair and scalp health. Surfactants like SLS clean but can cause dryness; moisturizers like glycerin add hydration; and silicones provide smoothness but may build up. Understanding labels helps avoid irritants. For sensitive users, hypoallergenic or natural options may reduce risks of reactions.
Tips for Choosing the Right Shampoo
To avoid issues like those in the review, select shampoos based on hair type (e.g., oily, dry) and concerns (e.g., allergies). Look for pH-balanced formulas, avoid known allergens, and read reviews. Patch-testing and consulting professionals can ensure compatibility. Regular hair care routines, including proper washing techniques, enhance results and minimize adverse effects.
