Amazing scent but left hair greasy with dandruff after two washes.

This shampoo's amazing scent couldn't prevent greasy hair by day two. After three washes to build lather, I got dandruff and scalp itchiness. Switching back to Ouai Detox solved these issues completely.

Shampoo Caused My Dandruff & Itchy Scalp

I really wanted to love this product. While the scent is AMAZING I feel that this is not suitable for my hair type.

First application in the shower doesn’t do anything on my hair, I have to give it like 3 washes in order to create foam and actually feel my scalp and hair clean.

My hair looks SO greasy by the 2nd day and I have started to have dandruff 😭 and my scalp is itchy.

This never happened with my previous hair product which was the Ouai Detoxing Shampoo and now I can’t wait to come back to it 😭

I have no doubt that this can be a great product for someone else but not for me unfortunately. I don’t think I would ever try this again.

Shampoo Basics & Tips

Why Shampoos Cause Greasy Hair and Dandruff

Greasy hair often results from shampoos stripping natural oils, triggering overproduction. Harsh sulfates can irritate the scalp, leading to flaking and itchiness. Dandruff may worsen if the shampoo disrupts the scalp's pH balance or fails to remove buildup effectively.

Importance of Proper Lathering

Lather helps distribute cleansers evenly. Low-lather shampoos like this one may leave residue, causing buildup that attracts dirt and oil. Always emulsify shampoo in your hands before applying, and rinse thoroughly with lukewarm water to prevent greasiness.

Scalp Health and Shampoo Selection

An itchy scalp signals irritation or fungal imbalance. Zinc pyrithione or ketoconazole in detox shampoos (like Ouai) combat dandruff-causing microbes. For oily hair, choose sulfate-free formulas with tea tree oil or charcoal to balance sebum without over-drying.

Hair Type Compatibility

Shampoos work differently based on porosity and oil levels. Fine hair gets weighed down by heavy moisturizers, while curly types need hydration. Patch-test new products on a small scalp section for 72 hours to avoid reactions.

Detox Shampoo Benefits

Clarifying shampoos remove silicones, pollutants, and hard water minerals. Use weekly but not daily—overuse can cause rebound oiliness. Look for apple cider vinegar or bentonite clay in formulas for gentle deep-cleansing.
