L’Oreal Paris Hyaluron Pure 72H Purifying Shampoo Review: Purifying Oily Roots, Hydrating Lengths

Balancing oily roots with dehydrated lengths is a common haircare challenge, particularly for those with hair prone to buildup. L’Oreal Paris Hyaluron Pure 72H Purifying Shampoo is positioned as a targeted solution, promising a purifying cleanse for oily scalps while delivering hydration to parched hair lengths. But how well does the evidence support these claims—and what should you actually expect from this formula?

What Is L’Oreal Paris Hyaluron Pure 72H Purifying Shampoo Positioned to Do?

L’Oreal Paris positions this shampoo specifically for people with normal or oily hair, oily roots, and scalps prone to residue and buildup. The brand states that the formula is designed to purify oily scalps and hydrate hair lengths, aiming to keep hair fresh, purified, and healthy-looking for up to 72 hours. According to the manufacturer, it removes impurities and up to 100% of residue compared to unwashed hair, and is intended to cleanse without stripping or weighing down the hair.

Formula and Key Ingredients

The ingredient list is fully disclosed and includes sodium laureth sulfate, cocamidopropyl betaine, salicylic acid, hyaluronic acid (as sodium hyaluronate), and fragrance, among others. Salicylic acid is commonly used in haircare for its ability to dissolve oil and remove impurities, helping to purify the scalp. Hyaluronic acid, on the other hand, is widely recognized for its moisture-attracting properties, which can help hydrate hair lengths. The formula is also described by the brand as non-stripping, aiming to cleanse effectively while maintaining hair’s balance.

Residue Removal and Purifying Claims

L’Oreal Paris cites product-specific testing showing that the Hyaluron Pure 72H Purifying Shampoo removes up to 100% of residue when compared to unwashed hair. This residue removal is a key differentiator for those whose hair is prone to buildup from styling products or environmental factors. The inclusion of salicylic acid supports the purifying focus, while hyaluronic acid is included for hydration. The brand also claims the formula keeps hair purified and hydrated for up to 72 hours, though this is based on the manufacturer’s own statements rather than independent long-term studies.

Usage and Suitability

The shampoo is intended for daily or regular use as part of a haircare regimen. Application directions specify focusing on the roots to target oiliness and scalp buildup, then working the lather through the lengths before rinsing. It is positioned for normal or oily hair types, especially those with oily roots and dehydrated lengths, or hair that is prone to residue and buildup. The suitability claims are clearly defined, but as with any haircare product, individual responses may vary and are not independently verified here.

Sustainability and Sensory Experience

The bottle is described as consciously designed and made from 100% recycled plastic, excluding the labels. The formula is also infused with what the brand describes as a fresh and luxurious fragrance, which may appeal to those who enjoy a sensory element in their haircare routine. However, fragrance preferences and sensitivities are highly individual, and no claims are made regarding hypoallergenicity or fragrance-free status.

What’s Not Established

While the shampoo’s purifying and hydrating positioning is supported by the inclusion of salicylic acid and hyaluronic acid, and residue removal is backed by product-specific testing, there is no independent clinical evidence provided regarding long-term scalp or hair health benefits. Suitability for specific hair or scalp sensitivities is not addressed, and the impact of daily use over extended periods is not specified. The absence of price information also means value-for-money cannot be assessed here.
