Hair Serum for Strengthening & Repairing Damaged Hair | Patent Pending Formula | Maleic Bond Repair Complex 05% | With Amino Acids, Argan Oil & Squalane | For Women & Men | 1.7 Fl Oz/ 50 ml

I don't think this smells quite as bad as other reviews say, but it's not really a good smell either. Some kind of musty funk going on with it but it's not so terrible I can't deal with it for an hour. That said, it does work extremely well for repairing and strengthening hair. I've been using it the last 2-3 weeks along with the Minimalist hair mask every wash day with excellent results after going overboard with bleach. My hair wasn't breaking off, but my natural curls were damaged enough to lose their curl and my overall hair was dry, frizzy, and tangled. Using this (and the treatment), my hair has regained a good amount of its curl but far more softness and shine than it had prior. It's immensely more manageable and I don't have the horrid frizz and static-y ends all the time now. I'm confident that the more I use it the more my curls will return.

First off the smell seems to be a hang up for some. And let me just say, there is one, but it isn’t an added scent, if that makes sense. It smells like marjoram or maybe rue? And old books. There’s definitely an herbal smell and probably not one that people would use in their diffuser, but I find it rather pleasant. Reminds me of an old library in a room with an antique leather chair. But it’s also not so strong that I can smell it once I put it on and pull my hair back. Not your typical hair products smell, but 🤷‍♀️ Aside from that, let me just say - I have been bleaching my hair to dye it pink since 1996 and am always looking for products to help keep my hair healthy. This stuff really made my hair feel smooth and soft. I’d recommend!

It works amazing the smell is kind of weird though. I have tried all the hair oil. Argan oil, Biosilk, Garnier sleek and shine, verb ghost oil, copper avocado oil mix, K18 I know it’s not oil but I am going to throw it in. This is the best. My hair is very fine and colored damaged. I have hard well water and live in the high desert. I have curly hair but it’s textured so it gets so frizzy. This makes my hair feel so much better, soaks in nicely isn’t greasy. Smells worst the first time you put it on but after a while it gets better and then I kind of like it. I would say though the smell can be off putting for some that’s why 4 stars and not 5. Worth every penny though. I love the bottle and how heavy it is. Plus the price point is amazing. I would try it.

Watch out for the smell, I was put off by that, it also has a weird texture, I didn't notice any improvement on my hair.

This serum smells exactly like brass instrument oil. I realized it too late as I had already started to put it on my hair. Unfortunately, I blindly bought it and didn't read the reviews first. I left the serum on my hair for an hour and then washed it out. As for the effectiveness, I didn't really notice much of a difference in my hair. I personally think there are much better products (that don't smell quite as bad) that you can use to repair your damaged hair. I will not be purchasing again.

I really like this product. I wasn’t sure about it at first but the results really do speak for themselves. After washing it out my hair feels like a million bucks. It’s so smooth, shiny, and soft. It makes my hair feel less damaged. It absolutely works. However, I didn’t give it five stars because the smell is pretty bad. I may be sensitive to it, but it’s pretty rough. Despite that, the product works SO well that if you really have damaged hair or it needs some love it is totally worth suffering the smell. I’m totally aware too that maybe this smell doesn’t bother everyone- to each their own. But just be warned it does smell, and I’d advise washing your hands after.

This isn’t a styling serum. It’s a bonding treatment. Directions say to apply to DRY hair, leave on a maximum of one hour and then to wash hair as usual. So why are folks using this any other way? I followed the instructions and absolutely loved the effects on my coarse bleached toned hair. While it did lift some of the toner out, that was easy enough to fix with my usual tinted conditioner. I just left it on a few extra minutes to make up for the difference. This bonding serum treatment is even more intense than the Minimalist Maleic Acid Bond Repair Mask, which can be used more quickly in the shower for 5 minutes. I thought that product was great but this serum knocks it out of the park in comparison. The serum does stink big time. But my results justify putting up with the scent. I should have put that in this review initially. I wouldn’t recommend using it as part of a styling routine because the directions don’t give that as an option. Using it that way could have negative effects. Otherwise I think such directions would have been stated explicitly on the packaging. So my advice is to use as directed for best results

This oil makes my dry hair so soft and really tames the frizz! Even my husband noticed! 😂

"Amazing! Transformed my damaged hair. Softer, shinier, and stronger after a few uses.

رائع ورخيص ومفعوله احسن من K18 النفشه مو بس تخف الا تختفي وما يخرب الشعر او يجففه بالعكس تحسيه صحي. المفروض ينحط على شعر ناشف يترك ساعه ويغسل بالشامبو وهذا عيبه الوحيد ان استخدامه فيه هالسالفه بس صراحه الكميه راهيه والسعر حلو والنتيجه اكثر من ممتازه واغناني عن K18

Wow — my hair hasn’t felt this strong/good in years. It actually does what it claims, which feels like a miracle these days. Pro tip: condition after shampooing, even though the directions don’t say to — my hair definitely needed it.

It is a really good serum, works well as it improved the texture of my hair. The smell is bit weird but I reckon its due to the formula. Great value for money.

Been using the Minimalist Bond Repair Complex for a while now, and I gotta say—my hair is loving it! It’s super lightweight, doesn’t make my hair greasy, and actually feels like it’s doing something. My hair feels smoother, less frizzy, and way stronger than before. Definitely takes time to show results, but patience pays off. If your hair’s been through heat styling or coloring, this is worth trying!
