Caldera Lab The Hair Serum Mens Thickening Serum for Thinning Receding Hair Supports Fuller Stronger-Looking Hair Dermatologically Tested

Love it, the hair serum is a solid upgrade if you want your hair to look healthier and feel softer. It goes on light, smells clean, and makes your hair look fuller without feeling greasy. The ingredients are legit, including peptides, caffeine, and plant extracts. While it’s not meant to regrow hair, it definitely improves how your hair looks and feels. It’s on the pricier side, but worth it if you’re aiming for a clean, high-end routine. Read more

I got this about a month ago, but admittedly I keep forgetting to use it consistently. For that reason, it is hard to judge the effectiveness of the product. I always find these things difficult to judge anyway, because the changes would be so small it will take quite some time to really tell if it is effective or not. That being said, I will continue to use it and try to be more consistent with it, so hopefully I will have more information later on. This product comes in a thick, dark glass bottle with an easy to use dropper in the lid. The instructions suggest using 1-2 full droppers each time. I generally stick to one dropper and that seems to be enough. It says you can use it on wet or dry hair and you do not rinse it out. I have tried on both wet and dry hair and it works great on either. I was concerned it would leave my hair looking greasy with that much serum in it, but I don't notice it at all once it dries. It doesn't have a tingly feeling necessarily, but I can tell that it is there after I use it. It is almost a cooling sensation I guess. That is not a bad thing as it doesn't bother me at all. I have very thin hair and I don't want to lose any more of it, so I have been trying to help it out. I recently found a shampoo that seems to be helping, so I figured adding this as well can't hurt. I can't tell yet if this is doing anything beneficial, but it definitely is not harming anything. I like that this one is a cruelty free option that seems to use good ingredients. It is hard to judge how long this bottle will last because I can't tell how much is still inside. The bottle is heavy and the glass is dark, so I have no idea how much is left. I am not sure if I will notice any difference by the time I finish the bottle, but will update my review if I do. Read more

I’ll admit—I was skeptical at first. Most scalp treatments I’ve tried in the past were greasy, hard to wash out, and left stains on my pillowcases. Not this one. Caldera Lab’s The Serum absorbs beautifully without weighing my hair down or making it look oily. I’ve even worn it out during the day with no issues. Best of all, I’m starting to see real growth—tiny new hairs in areas that haven’t had any in years. This product feels like a miracle in a bottle. If you’ve been struggling with thinning hair or slow growth, give this a try. It’s truly a game-changer. Read more

Pros: 1. Smells nice. 2. Comes with doppler. 3. Well packaged. 4. Sealed when I received. 5. Non greasy. So I only use a bit of it and my hair feels softer and healthier. The serum is not sticky. Easy to use due to the doppler provided. Cons: expensive and after using it for over than 1 month, I don’t feel it helps with hair growth. Read more
