8 Best Hair Glosses 2025 in the United States

Kristin Ess The One Signature Hair Gloss - Ruby is designed for those with light brown, medium brown, or red hair who want to enhance their color with vivid red tones. This in-shower treatment aims to boost vibrancy and shine, making hair look fresh and healthy between salon visits. It is easy to use; just mix two bottles, apply to wet hair, wait for 10-20 minutes, then rinse, shampoo, and condition as usual. The effect lasts for about 3-4 weeks with a single application, which is convenient for maintaining color without frequent touch-ups.

The gloss is liquid, silicone-free, ammonia-free, cruelty-free, and vegan, making it a good choice for those looking for a more natural and ethical product. It also excludes parabens and phthalates, which can be beneficial for people wanting to avoid these chemicals in their hair care products. However, it’s worth noting that this product is specifically for those with light to medium brown or red hair; it may not be suitable for those with significantly different hair colors.

Additionally, as it needs to be applied in the shower and left for up to 20 minutes, it may require more effort and time than some users might be accustomed to. The product's focus on shine and tone enhancement is excellent, but those looking for more substantial hair repair or conditioning might need to supplement with other products.

The Kristin Ess Signature Hair Gloss in Chocolate Cosmo Dark Golden Brown is designed for anyone looking to enhance their hair's shine and manageability. It’s an easy-to-use in-shower treatment that offers deep conditioning benefits. One of its standout features is its ability to create a protective shield over the hair, which helps in locking in color and boosting shine instantly.

This is particularly beneficial for maintaining hair color and preventing it from fading due to hard water minerals. The formula is ammonia-free, making it gentle on the hair and scalp, and it's not intended to lighten or fully cover greys, which might be a downside for those seeking to conceal grey hair completely. The gloss also smooths and softens hair from root to tip, which can make your hair more manageable and easier to style.

It is suitable for both men and women and is particularly advantageous for those with color-treated hair that needs a little extra shine and protection. However, it comes in a 2 fl oz bottle, which might not last long for those with longer or thicker hair. Additionally, users should be aware that it does not offer permanent solutions but rather a temporary gloss that will need reapplication over time.

The L’Oréal Paris Le Color One Step Toning Hair Gloss in Cool Brunette is a hair product designed to neutralize brassiness and add a cool tone to brown or black hair while enhancing shine and deeply conditioning the hair. It’s particularly effective for those looking to refresh their color without causing damage, thanks to its no-damage formula infused with coconut oil. This makes it a great option for people who want to maintain their hair’s health while adding a touch of color.

The product is vegan and free from harsh chemicals like ammonia, parabens, phthalates, sulfates, and mineral oils, which is a big plus for those with sensitive scalps or who prefer cleaner beauty products. Each tube offers up to three applications, and the color effect lasts around 10 days, making it a short-term commitment ideal for those who like to change up their look frequently. The in-shower application is user-friendly, requiring no mixing or gloves, which simplifies the process and saves time.

This hair gloss can be used on all hair types and textures, whether color-treated or natural. However, one limitation is that the color only lasts about 10 days, so frequent reapplication is necessary to maintain the desired tone. Additionally, while the product adds shine and conditions the hair, it might not provide drastic color changes, which could be a drawback for those looking for a more noticeable transformation.
