Softening and detangling conditioner without a bunch of ingredients. But one of those ingredients is Sodium Hydroxide. Say what?


It smells fresh and clean


I am a little surprised at this conditioner. I use very little store-bought conditioner right now because I usually make my own conditioners, leave-ins and deep conditioners. But Sodium Hydroxide, tho?! WTF? More about that later.

When I first received the Vidal Sassoon Pro Series tiny samples through, I immediately opened the Moisture Lock Conditioner first to test the consistency and the smell. I was impressed both with the consistency and the smell right from jump.

To be honest, I was ready to turn my nose up at it because…. what coily-headed Natural chick uses Vidal Sassoon?? LOL! I’m sure there’re some but you know how people jump to conclusions, right? 😛

But I rubbed some of the Moisture Lock Conditioner between my fingers to see how well it would absorb. At first, it felt blah. But then it couldn’t have been more than 10 minutes later and my fingers were soft. I mean, SOFT like I had applied lotion.

By the time you get around to getting a big bottle, I hope they haven’t changed the formula on you.

Wet hair

It does what it’s supposed to do. My hair was softer after shampooing. It didn’t melt my curls like when I first started using Suave Professionals SLEEK conditioner, though.

Dry hair

It’s a rinse off conditioner, so it would probably be wasted by being applied to dry hair.Make sure hair is at least damp if you’re going to test it out as a leave-in.


Sodium Hydroxide – Sodium Hydroxide? Sodium Hydroxide?! WHY COME? WHY COME THO? Sodium Hydroxide is that very caustic ingredient which makes a relaxer. In this formula, though, it is used as a pH adjuster and it’s the 3rd ingredient from the bottom of the list. They KNOW they could’ve come up with some other ingredient for that purpose.

Behentrimonium Chloride – AKA BTAC, Behentrimonium Chloride is used as an anti-frizz, conditioning and preservative ingredient. It has a 3 on the EWG’S Skin Deep website. EEE!!

Stearyl and Cetyl Alcohol – Yall know what these do. These are the FATTY alcohols, not the isopropyl alcohol that we were all warned to stay away from. Typically they function to help thicken and stabilize the emulsion (conditioner) to make sure it doesn’t separate. They both have a score of 1 on EWG’s Skin Deep website

Bis Aminopropyl Dimethicone – Oh no! A -cone!! According to, it’s a modified silicone which is supposed to help condition the hair. It’s also supposedly in products made by Pantene, Herbal Essences, Aussie, and Wella.

Benzyl Alcohol – Benzyl Alcohol is used mostly as a preservative and for its solvent abilities. It has a score of 5 on the EWG’s Skin Deep scale, making it a “moderate hazard”. By contrast, the controversial propylene glycol only has a score of 3 on that same scale. But Aussie 3 Minute Miracle Moist Deeeeep Conditioner (the whole thing) gets a score of 5 on that scale too. So, you decided whether or not it’s a deal-breaker for you.

Disodium EDTA – Disodium EDTA is used as a preservative and a chelator (helps counteract the effects of hard water). It’s meant to deactivate metal ions to prevent products from deteriorating and smelling bad.

Methylchloroisothiazolinone, Methylisothiazolinone – Both are preservatives with antifungal and antibacterial properties. However, it’s a known irritant to some people and both have a rating of 5 on EWG’s Skin Deep scale.


Softening conditioner. Sodium Hydroxide on the list of ingredients will surely turn off many a Natural though.

Short ingredient list
Noticeable softness
Smells good

Sodium Hydroxide is listed as an ingredient
Contains at least 1 cone
Sample size for the conditioner was waaaaay too small for a natural-haired chick.
