| Review | Augustinus Bader The Leave-In Hair Treatment

Augustinus Bader is breaking into the hair-game and I'm all for it! I've been a long-time fan of their repairing skincare range and this entry into haircare isn't a surprising extension for the brand. Along with a shampoo and conditioner, the brand has also released a variety of hair treatments. Since I am very hard on my hair by coloring it and styling it with heat, I use leave-in treatments often to help repair my hair. I was very excited to see a leave-in treatment from the brand that has proven to repair my skin so well. I am really hoping it would do the same for my hair.

The Augustinus Bader The Leave-In Hair Treatment retails for $50.00 USD and is available at Augustinus Bader and other retailers. This product is housed in a small blue plastic tube with a copper twist-off cap. This bottle is shockingly small for a leave-in hair treatment, it only contains 1oz. of product, which is significantly less than what I am used to for a leave-in treatment. Typical leave-in treatments usually contain at least 3oz. of product, which makes sense because you usually need quite a lot of product depending on how long your hair is. I am very disappointed at how little product is included but I would consider the treatment to be much more potent than a typical leave-in conditioner, it is actually more like a leave-in serum. Additionally, since the formula is so runny and you woul typically store this product upright with the cap on the bottom, I find the cap gets quite messy. You will need to be very careful when opening the cap to use it because the treatment easily runs out of the tube.

This leave-in hair treatment is a serum and not a conditioner formula or texture. The lightweight and runny texture allow the product to easily distribute throughout the hair so, you really don't need much product. I find that you only need about a nickel to a quarter-sized amount, depending on how long your hair is. I have a medium hair length at the moment and I feel like I need only a little more than a nickel-sized amount. Since this formula is so light and runny, it is best to use this product on damp hair. Just be sure there isn't too much water because it can wash away the serum instead of allowing it to absorb into the hair. I just thoroughly run this product through the lengths and ends of my hair and then I take the remaining up towards the roots. I only do this, not because the product is greasy in any way, but because My lengths and ends are much more damaged than my roots. I recommend focusing on the areas where you have the most damage or need the most nourishment in your hair. 

The product itself literally feels like a face serum! It is neither sticky nor is it greasy. It just disappears into the hair invisibly and you don't notice a huge difference initially but you will notice your hair is more brushable and smoother. When your hair begins to dry, that is when you will notice the big difference. Whether you air-dry your hair or use a blowdryer, you will notice that your hair dries with significantly less frizz, your hair will look smoother, and sleeker. When I typically air-dry my hair, I notice that my hair gets quite wild and frizzy, even with product placed on it. However, when I use this treatment, my hair looks much smoother and less frizzy! It is even more of a significant difference when you blowdry your hair!

Like I said, when I first applied this product to my hair, I didn't notice anything amazing but when I dried my hair with a blowdryer, my hair looked smoother, softer, sleeker, and it even gave my hair some volume! I usually have to use a separate volumizing product from my leave-in product to get volume in my hair when I blow it out but this serum does it all! I had been looking for a product that would give me that silky, sleek, celebrity blowout look, and this leave-in combined with the Augustinus Bader The Hair Oil (review coming soon), is the perfect combination for achieving the most flawless blowout! 

While this formula does seem to smooth out the texture of the hair follicles, reducing frizz and unwanted texture, it is not nearly as hydrating as I expected. It does seem to hydrate and protect the hair from heat because I notice the difference in my hair after blowdrying my hair. Typically, post-blowdry my hair feels drier than when I use this treatment. Still, I find that I need to apply hair oil after my hair drying because my lengths and ends still feel dry, just not as dry as when I use other leave-in treatments. 

I have been using this hair serum for over a year and I am still amazed by the results every time! There's nothing that compares to this formula. I found that long term use has made my hair feel a lot stronger and healthier. I don't cut my hair as often as I should, only about every six months, which means I really rely on product to help strengthen an treat my hair in the meantime. I feel that this treatment keeps my hair so healthy, despite the lack of hair cuts and the regular heat styling. It makes my hair styling so much easier and it delivers the BEST RESULTS I have ever received from a hair product before. It just leaves my hair so soft, smooth, an silky.  


The full ingredients from the website are listed here:

The brand touts that the hair range is "powered by TFC8® technology" but doesn't necessarily say it contains TFC8® technology. From what I see in the full ingredients list, their exclusive complex is not included in the formula because it would be listed as PALMITOYL TRIPEPTIDE-8 but I don't see this peptide complex in this formula. I believe what they mean by "powered by TFC8® technology" is the formula is based on similar research but not necessarily the same technology. To me, this is the brand using their formula's notoriety to market their other products. I personally find this a little deceptive. I don't think the brand needs this over-the-top type of marketing because their products really speak for themselves.

Augustinus Bader The Leave-In Hair Treatment Review


Based purely on the size and the amount of product in the tube, it definitely feels like you aren't getting value out of this product and it doesn't seem worth it but, the product itself is phenomenal! I guess that's the nature of luxury products. You don't get much product but when it's good, it's phenomenal and well worth the price! I only wash my hair about once a week so, using this product weekly doesn't break the bank for me. The results are honestly unlike any leave-in hair product I have used before! There is nothing that compares to this formula! My hair is just so much stronger, healthier, softer, silkier, and shinier when I use this treatment. I have never really been a "hair-person" and felt the need to spend a lot of money on my hair but this product just makes such a huge difference in my routine. I was skeptical that they brand was going to deliver amazing haircare but I shouldn't have been so skeptical because they really have yet to release a product I hate. I HIGHLY RECOMMEND this product and I urge you to give it a try! Warning, you may just fall in love with it! Be careful! I have no regrets about this product and I will be continuing to repurchase this product throughout my lifetime!
