10 Best Dry Hair Treatments 2025 in the United States

Olaplex No. 7 Bonding Oil is designed to address the needs of individuals with dry or damaged hair, making it a versatile option suitable for all hair types. One of its standout features is its ability to enhance shine significantly—by up to 125% compared to untreated bleached hair. This makes it a great choice for those looking to add a glossy finish to their locks. With its humidity-resistant formula, it provides impressive frizz control for up to 72 hours, which is ideal for anyone living in humid climates or struggling with frizz-prone hair. The product also offers heat protection up to 450°F, making it a valuable addition for those who frequently use styling tools. Furthermore, it helps reduce breakage by 77%, strengthening the hair and promoting a healthier appearance over time.

Some users may find the oil's unscented formula less appealing if they prefer a fragrant product. While it is suitable for all hair types, those with very fine or oily hair should apply it sparingly to avoid weighing their hair down. Additionally, at 1 fluid ounce, the bottle might not last long with regular use, especially for individuals with longer or thicker hair.

Olaplex No. 7 Bonding Oil is particularly beneficial for people with dry, damaged, or color-treated hair seeking shine, strength, and protection from heat and humidity. Although it may not cater to those looking for a scented treatment, its effective formulation makes it a strong contender in the dry hair treatment category.

The Kerastase Nutritive 8H Magic Night Hair Serum is designed to intensely nourish and hydrate dry hair overnight. One of its main strengths is its ability to protect hair from pillow friction, which can reduce frizz and leave hair looking smooth and shiny by morning. The inclusion of plant-based proteins and niacinamide helps to provide essential nutrients and lock in moisture, promoting long-lasting hair strength. It's suitable for all hair types, making it a versatile choice for anyone with dry hair concerns.

The application is straightforward: simply apply a small amount to dry or damp hair before bed and leave it in overnight, with no need to rinse in the morning. This makes it a convenient option for people with busy schedules. The citrus scent is pleasant and refreshing, and the product is free from parabens, which is a plus for those conscious of avoiding certain chemicals in their hair care routine.

However, at 3.04 fl oz, the volume may seem small for regular use, especially if used three times a week as suggested. While it is highly ranked in the beauty and personal care category, the price point might be on the higher side for some users, given the premium ingredients and brand. This serum could be a great addition to the nighttime routine for those looking to deeply nourish and hydrate their dry hair, though its cost and size might be points to consider for some users.

The Olaplex No. 6 Bond Smoother is a versatile leave-in styling hair cream designed to smooth, condition, and strengthen hair while providing frizz control for up to 72 hours. This product is suitable for all hair types, which makes it a good option for anyone dealing with dry hair issues. One of its primary strengths is its ability to moisturize, detangle, and repair damaged hair, reducing breakage and protecting against heat up to 450°F.

The cream also helps to speed up blow drying times, making it convenient for everyday use. Additionally, it is vegan and free from harmful ingredients, which is a plus for those looking for a more ethical choice in hair care. However, the product's small size (3.3 fl oz) might not last long for those with thicker or longer hair who require more product per use.

In essence, Olaplex No. 6 Bond Smoother is a robust option for anyone seeking to manage dry hair with added benefits of frizz control, heat protection, and hair health improvement.
