I’ve been using Olaplex No. 0 as the first step before my bond repair routine, and it has been a great addition. The spray applicator makes it easy to distribute evenly through the hair, and it leaves my hair feeling well saturated without being messy. When I follow it with the next treatment, my hair feels noticeably softer, smoother, and easier to manage. It’s especially helpful for hair that has been damaged by coloring or heat styling. A little patience with the process is worth it for the results. I would definitely recommend it as part of a complete repair routine.

I have historically had a lot of “volume” in my hair (according to others). My hair was “thick” but had a lot of frizz and what felt to me like dryness. For this, I started using the Redken system, and experienced significant results, but nothing like this. I added Olaplex to my routine once a week, using the whole Olaplex system (No. 0, No. 3, No. 4, No. 5, and No. 7) I have seen substantial—and honestly, shocking—improvement. The FIRST TIME I used these products I blow dried my hair and my hair (which is normally very wavy and frizzy) took on the appearance of being straightened without using the flat iron. I was shocked. I didn’t realize how much damage was in my hair, even though I haven’t dyed it in years and maybe once every three months (or longer) flat iron it. I knew hair could get damage from sun and the just living, but never understood the extent of it until I tried Olaplex. My hair looks healthy, shiny, and soft. Absolutely amazing results.

I was honestly surprised by how well this worked. My hair felt stronger, softer, and looked healthier after using it with No. 3. It made such a difference on my dry, damaged ends without weighing my hair down. A little goes a long way, and now it's a staple in my hair routine. Definitely worth it if your hair needs some extra love!

Works fabulously when paired with the no 3. The only reason I took one star off is because the spray bottle is awful. I transferred it into my own spray bottle. It only comes out in a stream and you end up wasting a ton of product. I have hair that is about 3/4 down my back and it takes 3/4 of this bottle to saturate it. Is it worth it? Yes! I used the no 3 alone before this came out and liked it, but adding this really does make a difference.

I've been using Olaplex products for about four years, and No. 0 is the first step in my favorite deep-treatment routine. I use it together with No. 3 before coloring my hair, and I truly believe this combination has helped keep my hair healthy despite years of coloring and heat styling. I spray No. 0 generously on dry hair, apply No. 3 over it, cover my hair with a cap, and often leave it on for several hours while doing housework before washing it out. My hair always feels softer, stronger, and more manageable afterward. I have naturally curly hair, and this treatment helps reduce frizz, improve shine, and keep my curls looking healthier. It also helps when I decide to wear my hair smoother and straighter. I've continued this routine for years because I can genuinely see and feel the difference. No. 0 works best when paired with No. 3, so I consider them a team rather than separate products. It's not inexpensive, but for me it's worth every penny because it helps maintain the health of my color-treated hair. Pros: Excellent when used with No. 3 Leaves hair softer and stronger Helps reduce frizz Great prep before coloring Noticeable long-term results Cons: Works best when paired with another product Higher price point

I have bleached hair that I apply vivid colors to. I've been using the Olaplex system (No3, 4, &5) for years. I've recently added this into my routine as I was told that it can help even more with reducing breakage and helping with the integrity of my hair. This helps reduce breakage and keep my hair feeling strong even through the damage that bleaching causes. It is expensive and it's not a large bottle but I only use Olaplex a couple times a month as I wash weekly and alternate with a different shampoo/conditioner so this lasts me a while.

I lost all of my hair from brain surgery and the chemotherapy-type medications that followed. Over time, and because of Olaplex, I’ve been able to grow full, healthy, shoulder length hair. There is NO doubt it is from using Olaplex. I do not take any type of hair growth supplements, and I had zero results from many, many other hair product I’ve tried over the years. Currently, I use: Olaplex 3: Hair perfector Olaplex 4: Shampoo Olaplex 5: Conditioner Olaplex 7: Bonding oil Olaplex 8: Hair moisture mask Olaplex 9: Bond Protector Olaplex volumizing blow-dry mist Giving anything from Olaplex an “average” review is tough. A small problem is that I personally find the spray difficult and awkward to use. My main issue is just that it offers no additional benefits to me that aren’t already provided in the other Olaplex products that I currently use. For me, there is simply no point nor benefit in using it. However, if you aren’t using other products by Olaplex, this may be a wonderful product for your hair. Olaplex is a miracle product line for me, and for many other women facing the same problems. It was originally recommended to me by a member of a support group I attend. As a matter of fact, almost every woman in that group uses their products. Yes, it is a big financial commitment, but since many women (myself included) have much of their femininity and self esteem directly linked to their hair, it’s worth it!
