Is Olaplex No 7 Bonding Oil Worth It?

Among the dozens of products and brands that have gone viral on TikTok in recent years, the Olaplex line is among the few that has managed to stay popular thanks to the quality of the line and its healing properties.

According to Allure, Olaplex's most popular item is its No. 3 Hair Repair Perfector. The product revives damaged hair by reducing breakage and strengthening the hair. The hair perfector is applied to damp hair from root to tip and is suitable for all types of hair. "Olaplex no 3" has over 90 million views on TikTok, with users with straight strands to kinky curls singing the praises of what Olaplex did for their dry, damaged, and dyed hair.

The Olaplex numbers indicate which step of the process you should use the product in, ranging from zero to nine. While No. 3 and the No. 5 bond maintenance conditioner are the bestselling Olaplex products at Sephora, what about the rest of the line? Another Olaplex that's gaining prominence is its No. 7 Bonding Oil. With the other products receiving high praise, is the bonding oil worth your money?

According to the Olaplex website, the bonding oil revives damaged hair, strengthens and protects the structure of the hair, and restores the texture, giving your strands a healthy appearance. It's a two-in-one product, used for taming frizz and protecting the hair from heat. It also offers UV protection, which is great, because most people forget that their hair needs some type of sunscreen, too.

The bonding oil is gluten, nut, paraben, phthalate, and cruelty-free and also vegan and is pH balanced, which helps to protect your hair against bacteria-causing fungus and breakage, says the Minnesota School of Cosmetology. The oil costs $30 for a 30 ml bottle, which definitely isn't the largest hair oil or heat protectant.

As for the effectiveness of the oil, Olaplex says they use their own patented ingredient, Bis-Aminopropyl Diglycol Dimaleate, to repair the hair from the inside out. The bonds of our hair that keep it strong, known as disulfide bonds, can be broken down due to heat damage, chemical treatments, humidity, and a host of other things. Olaplex's key ingredient works to repair the broken structure, bonding them together again.

The oil has a 4.7 rating on Amazon and is a #1 bestseller item. Reviewers praise the oil, saying that it has worked wonders for their dry and damaged hair and that a little bit goes a long way. Based on the reviews and science, the No. 7 Bonding Oil is definitely worth your money.

The Olaplex No. 4 Bond Maintenance Shampoo cleanses hair and nourishes strands. It contains rosemary oil, which strengthens the hair and stimulates growth. It tames frizz and repairs split ends to reveal shiny, healthy hair. The Allure Readers' Choice Award Winner works on all hair types and is cruelty-free and vegan.

Its No. 9 Bond Protector Nourishing Hair Serum is a silicone-free serum that offers protection from pollution and heat up to 450 degrees. The leave-in serum detangles and smooths the hair with its weightless formula. It contains red algae extract, which has antioxidants that strengthen and thicken hair strands.

The Olaplex No. 8 Bond Intense Moisture Mask contains safflower seed, avocado, rose hip, and rice bran oil, along with glycerin, to provide the hair with intense moisture, reviving damaged strands of all hair types. The vegan mask doubles the shine of hair and quadruples the moisture, based on clinical trials.
