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 Rich Hydration Mask is designed especially for dry, medium to coarse, or thick hair types that need deep moisture and frizz control. Its standout feature is Biomimetic Cuticle Technology, which helps lock in hydration and seals the hair cuticles for up to five washes, reducing moisture loss and protecting hair from breakage. The mask also includes avocado and shea oils that provide nourishing softness and shine, making hair feel smoother and look healthier.

Application is straightforward—you apply it to wet hair after shampooing, leave it on for 3-5 minutes, then rinse, using it once a week for best results. This treatment excels at reducing frizz all day, even in humid conditions, and strengthens the hair over time. While it’s great for thicker hair textures, those with fine or very thin hair might find it a bit heavy. As a cruelty-free option, it suits users who prefer ethical beauty products.

This mask is an excellent choice for anyone with dry, coarse hair looking to boost moisture, reduce breakage, and tame frizz with a relatively easy-to-use weekly treatment.
