Added the Good Lab Blooming & Thickening Hair Serum to my daily regimen, and am entirely pleased with the results. While the product itself is lightweight, my hair definitely feels thicker, and healthier after a couple weeks of use. Really like that the product uses natural ingredients (guava leaf extract, nettle leaf, saw palmetto berry, etc, and NO HARSH MINOXIDIL) and is free from most everything that I would normally find objectionable in a product: Fragrance-free, Sulfate-free, paraben free, and cruelty free (certified by PETA). Very happy with the price point, and it works great with the other good lab products I have purchased. big upgrade over the standard stuff. Read more

Be patient for the results, they are not going to show up at first, but after almost a few months of constant use it will surprise you. I use it every time after washing my hair while they are still wet and massage it very softly to make sure that it covers the scalp everywhere. In my opinion using it for clean and wet hair has the most effect, but definitely you can try it on dry hair as well. It is the first hair product that made my hairs looks thicker. Read more

I like the shampoo and conditioner a lot- leaves my hair soft, manageable, and healthy looking. I added in this serum as I hoped to gain hair density or at least reduce loss (or reduce cycle frequency and/or duration). I dont have trouble growing my hair, I have trouble keeping it. So my hair is long, but much less dense than previous years. I transitioned from minoxidil to this. I wont do that again, as any gains I got from minoxidil were lost-- and I do contribute some of that to not using this as consistently as I did that. I'll explain what went into that below. This serum helped the condition of my hair and scalp, so I think it works well with minoxidil instead of in lieu of it. I likely wont continue with the serum for a few reasons.1. there was no instruction as to how to use this product. It is a dropper bottle, and I pretty much just used it like I did with minoxidil-- massaged whatever I pulled with dropper and distributed all over scalp, primarily at crown. Was this the correct way to do it? no idea. *2. It does say to apply to clean hair. Well, many of us do not wash our hair every single day. I have long curly hair that leans dry and there is no need to wash it daily. So I am either applying this to unwashed scalp daily or it only gets applied a few times a week. Hence the lack of consistency. So right here it eliminates some would-be users if it has to be on a fresh washed scalp.3. the dropper is uncomfortable. I do not want to drop it from the dropper. I want to run it across the scalp so as to keep it from getting on my hair. The dropper is a little sharp feeling (at least my bottle that I received). I like the dropper style, and my thought is that if I were to buy this again, I would use a dropper from an old minoxidil bottle instead.4. How long should this bottle last? Since I had no idea how much I should use, I often wondered if I used too much or too little. Any new hair treatment needs to be given 4-6 months of consistent use to see results, if any. I know the shampoo and conditioner helped, and this serum has great ingredients that will help existing hair and scalp health.. but the inconsistency on my part from lack of instructions as well as expectation of using on fresh washed hair made it impossible to see if I could get benefit from it. * "It is best applied to damp hair after showering. We recommend visually splitting your scalp into 4 sections/quadrants. Depending on the amount of hair, use around 3-5 drops per quadrant. I like to drop into fingers and work into scalp. The remaining amount on your fingers you can work through your hair. It is perfectly fine to use the serum many times a day. That being said, it is important that the scalp/hair is clean" (--I saw this written in the community question section of this page. Including this on box or in a leaflet would have been greatly helpful)The ingredients are of quality, the products work well together. I have since gone back to minoxidil, and once I have stopped the current shedding phase, I may buy another bottle to use as a support product. For that, I give it 4 stars. Read more

I had doubts about it, but after trying it out for a few weeks, I saw growth in my hairline. I am 21 years old and don't have a receding hairline, but my forehead is naturally big and I wanted the thinner hair in front to be thicker, so it does not look like I am balding at a young age. THIS IS HOLY GRAIL RIGHT HERE. Disregard castor oil because that stuff is so hard to be diligent with, especially because you have to put it on for 30 minutes and it leaves a greasy residue. That stuff is too much work. As for Good Lab, you can use 3-4 drops after you shower and it is not sticky at all. I tend to have VERY oily hair the next day and I was worried I would have to double shower after using the serum, but the consistency is like water. I told my dad, who is balding, to try it out and now we are purchasing our second bottle. If it works on my dad who seriously needs it more than I do, I will update!! Read more

I've been using this product for a couple of years. It does a pretty good job of thickening my hair. The last two bottles I received I noticed the texture of the serum was different. It was always thick and a milky white color. It now looks brown and is the consistency of water. It doesn't seem to work as well. Might hve to find a different product.UPDATE:The seller reached out to me and offered an explaination as to why the product could look different. They told me that the ingredients are all natural and depending on when the batches were made that might alter texture. They garanteed me nothing has changed with the serum and I believe them. They offerd me a refund on both bottles which I didn't take. They are sending me a bottle out of a new batch. The serum seems to still be working. I just have to use a little more because its thinner. We'll see with the new batch. Anyway I'm sticking with them. Just a side note they have great customer service. All companies should be this way Read more

Product does not have much of a scent. It is not too thick. It does not dry completely and leaves a slightly greasy layer, so I will be using this as leave in treatment overnight and days when I slick my hair back.I just received it, hair takes min 4 to 6 months to judge any true regrow, so I am always skeptical of reported results seen sooner. however the mixture of ingredients used are highly desirable and perhaps for those with stress related hair loss or in the early stages it MAY, but I bought this more as a scalp preparation to used in conjunction with a medication topical solution for more advanced hair loss. It is also worth a try if you want to enhance existing hair condition, which should be seen in 1 to 2 months.So if the ingredients are as stated and in proper amounts, this would be a desirable product and at a decent price compared to others out their.
