✅ SMELL : Rosemary hair oil smells really good. I put it in my hair and did a slick back bun. I could smell the rosemary all day it's nice. And the slick back worked really well, btw. ✅ SIZE : The bottle is 2 oz so if you don't take note of that the bottle will feel small when you received it lol. But it is a dropper application so it will last you a long time. ✅ INSTRUCTIONS / EASE OF USE : The oil comes with a derma roller but I found it a bit harsh on my scalp to use the derma roller AND my brush. The brush is all I need. ✅ FUNCTIONALITY / COMPATIBILITY : I use this oil as a pre-wash because I have oily roots and I don't want to use it post wash and get oilier quicker. But I still want the benefits of rosemary oil for hair growth and fullness. ✅ QUALITY / VALUE : I would recommend this. The bottle and packaging are well made, good quality. With a dark bottle to protect the oil. The dropper is glass. With a nice smell and easy application this is easy to incorporate into my hair care, especially for hair up days. My husband doesn't struggle with oily roots like I do and he's able to put a tiny bit straight on his scalp whenever he wants and will look just fine. Read more

This rosemary oil has a kind of herbal scent and feels like a well made blend, but a little goes a long way. I’ve been using it for a short time and my scalp already feels more moisturized and less irritated and I think I’m losing less hair in the shower. The derma roller is a nice touch, it does seem promising for regrowth on my thin, curly hair. Just a warning that it left a little stain on one of my white pillowcase. I just use it before my shower to prevent that. Overall, it feels like a solid scalp treatment with good ingredients. Read more

I was excited to try this Rosemary Hair Oil by Botanic Heath, because I've liked other products from this brand and, also, I've noticed some thinning of the hair at my temples, which is a very common thing in perimenopause. This hair oil contains the following ingredients: grape seed oil, jojoba oil, sesame oil, castor oil, Vitamin E, rosemary oil, and Biotin. Not surprisingly, it does have a very strong scent and an oily texture. The scent makes me think of rosemary oil plus menthol or eucalyptus. The oil is hydrating and nourishing, though it is oily enough that I would not use it every day unless I planned to wash my hair afterward. Otherwise, my scalp would become too greasy, plus the smell is rather strong. But this is a great treatment to use about 30 minutes before showering and washing hair. I have to be quick and careful with the application, because the dropper tends to release the drops of product very quickly and continuously, and I don't want to drip this on my clothing. It also comes with a very nice and somewhat intimidating derma roller, but I have only used my fingers to massage the oil into my scalp so far. I might try the derma roller at some point later, but it's easy to work into the scalp with my fingers. So far it has not irritated my scalp, but I only use it about twice a week, on the days that I wash my hair. It's too soon to tell if this will be as beneficial as I hope, but it has several ingredients that are good for scalp health and hair growth. The bottle is amber glass for protection from light, and I think it should last several months. This hair growth oil was made in India and its PETA approved. While it is too soon to tell if this oil is making a difference yet, it is packed with beneficial ingredients and lacks other harmful ones, so I'm hoping that this will help. If it is effective, it would be a very good value, and the price is very affordable. Plus, it comes with a very nice derma roller, making it an even better value. Read more

It smells great! I've used rosemary oils before but the additional oils in this one really make it a star. I haven't used it long enough to notice any hair growth, but I have noticed less hair loss. It leaves my hair very soft, and I'm able to use a little every day without it adding a noticeable greasiness. I do have pretty dry hair though. This is a quality hair oil and seems to be effective.

I got the 2oz bottle its a good size bottle considering the amount you will use. The smell is amazing I use it as a prewash treatment for me it does make and leave my hair oily and honestly I don't want to go around all day smelling like Focaccia even though it smells good. This product has to be used over a course of weeks to months. Until you achieve the goal that you're trying to achieve. Rosemary is a good stimulant and it comes with a nice derma roller which does take a little bit of time to getting used to and the first few sessions of using it it did hurt but. I figured out not to stab my head and to gently roll it and then apply the Oil. The bottle is glass, the dropper is glass, which is nice. It'll keep the longevity of the oil. The derma roller is plastic which is nice. It's easy to clean. Again, I use this as a. Pre wash treatment I tend to have oily hair So for me it works as a pretreatment. I haven't noticed any new hair growth but I will continue to use this and hopefully in due time with proper diet and this oil. Will help. Read more

This Botanic Hearth rosemary hair oil feels thoughtfully put together, especially for anyone focusing on scalp care and overall hair health. The oil itself is lightweight, absorbs well, and doesn’t leave a sticky or heavy residue when used sparingly. The rosemary scent is fresh and herbal without being overpowering, and the dropper makes it easy to control how much you use. I found it works best as a pre-wash treatment, where it nourishes the scalp and adds softness and shine to the hair without weighing it down. The glass bottle feels sturdy and premium, and the included derma roller is a nice bonus for those who want to add scalp stimulation to their routine. While results like thicker hair or new growth naturally take time and consistency, this oil feels gentle, well-formulated, and easy to use regularly. Overall, it’s a solid option for anyone looking to support scalp health and hair strength with a non-greasy rosemary-based oil. Read more
