10 Best Deep Hair Conditioners 2025 in the United States

Redken All Soft Conditioner is designed specifically for dry hair, making it a solid choice if your hair needs extra moisture and softness. Its main active ingredient, argan oil, is well-known for nourishing and hydrating hair deeply from root to tip. The conditioner has a liquid, smooth texture that’s easy to apply and spreads well through your hair. It works best when used after shampooing and rinsed out, and it’s gentle enough for color-treated hair, which is a big plus if you want to keep your color vibrant while improving softness. The scent is pleasant but not overpowering, fitting nicely into a daily routine without being distracting.

One of the notable benefits is that it can provide up to 15 times more conditioning when paired with other products from Redken’s All Soft line, which could be helpful if you want a complete care system. On the downside, if your hair is very oily or fine, this conditioner might feel a bit heavy or weigh your hair down. Also, since it’s targeted at dry and brittle hair, it may not be the best option if you have other concerns like scalp issues or need volume.

This moisturizing conditioner is best suited for those looking to restore softness, shine, and manageability to dry hair with a straightforward application.

The Olaplex No. 5 Bond Maintenance Conditioner is designed to repair, strengthen, and nourish all hair types. Its standout feature is the use of Olaplex bond building chemistry, which helps restore internal strength and moisture levels. This results in hair that feels soft, manageable, and shiny, making it a strong contender for those looking to improve their hair's health and appearance. The conditioner is suitable for all hair types, which is a significant plus, as it broadens its usability across different hair textures and conditions.

Its consistency is creamy, making it easy to apply and distribute evenly through the hair. The application time is standard and does not require an extended period, which is convenient for regular use. The scent is mild and pleasant, not overpowering, which is ideal for those sensitive to strong fragrances. However, the price point might be higher compared to other conditioners on the market, which could be a drawback for budget-conscious users.

Additionally, while it claims to work for all hair types, individuals with very specific hair concerns might need to pair it with other specialized products for optimal results. The product comes in an 8.5 fl oz bottle, which is decent but might run out quickly with regular use, particularly for those with longer or thicker hair. The Olaplex No. 5 Bond Maintenance Conditioner is a high-quality product that offers substantial benefits in terms of hair repair and maintenance, though its cost and the need for complementary products in some cases should be considered.

The Olaplex Wash and Shine Hair Kit seems like a comprehensive solution for anyone looking to improve their hair health. It includes a shampoo (No. 4 Bond Maintenance Shampoo) and conditioner (No. 5 Bond Maintenance Conditioner) that work together to strengthen and protect hair, reducing breakage, frizz, and split ends.

Additionally, the No. 7 Bonding Oil boosts shine and softness while providing up to 72-hour frizz control and heat protection. This kit is suitable for all hair types, which makes it versatile. The ingredients list is quite impressive as it's free from sulfates, parabens, phthalates, phosphates, cruelty, nuts, and gluten, catering to those with specific sensitivities or preferences for certain ingredients.

The liquid form and easy application are practical for everyday use. Despite minor issues, this kit offers a robust solution for multiple hair concerns—mainly anti-breakage and anti-frizz benefits.
