I had my hairline receding from years of tying my hair back tightly, but after using this scalp serum for about two months, I was amazed to see new hair growing along my hairline and even on the top of my head.

After seeing my mom's hair grow after using it, I also tried it on weekends. My hair feels noticeably stronger and has even grown some small baby hairs. I've also noticed a significant reduction in the amount of hair breakage compared to before.

I’m in my early 20s, and my main concern is that my crown area looks more noticeable. This is my first time using a scalp care product, and I figured it’s best to start caring for it while I’m young.

I use it 3–4 times a week, applying it after washing my hair at night and rinsing it off in the morning. It’s really helped with my sensitive scalp, which used to turn red after haircuts. The soothing scent has also made it a nice part of my bedtime routine. Initially, I just wanted to maintain a healthy scalp, but I’ve noticed improvement in the crown area too. And remember, good sleep helps! Highly recommend giving it a try!

My issue has been my thinning hairline on the forehead. It's sparse in places, especially noticeable when I tie my hair back. I even considered hairline tattoos or hair transplants at one point. What caught my attention was the natural aspect of this product, so I felt safe trying it out for maintenance. If it works, I won't have to worry about any potential side effects from medication. I tested it and didn't experience any breakouts, so I've been using it generously. Plus, the scent is incredibly soothing, making me want to apply a bit more than usual. It feels really calming and relaxing. I didn't expect it to work so quickly. I've only used one bottle so far, applying it evenly across my scalp with extra attention to the hairline. I can feel a noticeable difference, especially when I tie my hair back, lots of new growth.

As a toddler mom, it is so hard to be consistent with using this product so once in a while I try to squeeze in three consecutive days of application. The reason why I still invest time to do the minimal work is because there’s actually result!!

I’ve always had a receding hairline from tying my hair too tightly over the years, but after using this scalp serum for about two months, I was shocked to see new baby hairs growing along my hairline and even on the top of my head. I use it 2–3 times a week, applying it and massaging it in with a brush, and honestly, the difference has been super noticeable.

The scent is really calming, not that strong, artificial smell and it doesn’t make me break out. Even if I skip washing my hair for 2–3 days, my scalp doesn’t smell bad like it used to. Plus, after I wash my hair, it feels so light and fluffy like, by day three, it still looks good, and my friends couldn’t even tell I hadn’t washed it!

This stuff works. Seriously, if you’re thinking about it, just go for it. I'm already ordering another bottle.

My mom struggled with severe hair loss, especially around her hairline, and even Rogaine didn’t help. After using this for a month, she saw tiny baby hairs growing back! She now applies it every two days, massages it in, and washes it off the next morning. Hair fall on the floor has reduced a lot, and her scalp feels healthier. The natural ingredients, quick absorption, and soothing herbal scent make it perfect—no greasiness or artificial smell. Honestly, it’s an amazing product for the price!

After seeing my mom’s results, I started using it on weekends. I apply it at night and wash it out the next morning. My hair feels stronger, and I’ve noticed fewer breakages. The scent is so calming—it’s become part of my self-care routine. Highly recommend!

After using it, my scalp noticeably smells better and tends to get less oily over time.

It also feels fuller and more voluminous. Sometimes, I even apply it to my face without any issues! My skin feels healthy too! One day, my hairstylist remarked, 'Hey, you've got a lot of new hair growth!' I asked her, 'How long do you think it's been growing?' She replied, 'About 2-3 months.' I thought to myself, that's around the time I started using the oil! 😆

The hairline at my forehead has grown a lot, and the new hair comes in all sorts of thickness, some thin, some thick. The scent is fantastic and super relaxing before bed. Even though it’s oil based, it doesn’t feel greasy at all.

I use it 4–5 times a week and always leave it on overnight. I’m currently on my third bottle. At first, I wasn’t as consistent, but now I use it regularly. I didn’t take progress photos, but after washing my hair, I noticed significantly less shedding. One day, my husband even told me, “Your hair seems fuller!” (And trust me, it takes a lot for a guy like him to notice anything.) I’ve also noticed a ton of baby hairs growing, especially around my forehead hairline, and the new growth comes in all sorts of thickness.

Hair appears fuller, thicker, and denser in just 3 months

DAY 0 POOR SCALP HEALTH

Research indicates that many modern hair loss cases result from telogen effluvium*. Stress, irregular sleep, poor nutrition, and other factors can cause hairs to transition from growth to resting, leading to issues like poor scalp circulation, insufficient nourishment of hair roots, significant loss, thinning, and receding hairlines. Longer resting phases can further reduce hair density, and hair is more likely to fall out earlier than expected.

DAY 30 THE EVOLUTION BEGINS

Each hair has different phases: Anagen, Catagen, and Telogen. After starting scalp care, you usually enter the resting phase first, where unhealthy hair sheds to make room for new growth. New hair begins growing from the follicles again, which takes about 3 to 4 months. With consistent care, the scalp gradually restores a healthy environment, promoting better blood circulation, reducing hair loss, and strengthening the hair roots.

DAY 60 STRENGTHENED SCALP RESILIENCE

Witness stronger hair roots leading to fuller-looking hair, lessen hair thinning and decrease hair fallout. With scalp care, the roots gradually grow stronger and more secure. During hair washing and combing, a significant reduction in shedding becomes apparent. Moreover, observe a well-moisturized scalp, alleviating any feelings of tension.

DAY 90+ APPEARS FULLER, STRONGER, AND HEALTHIER

Expect changes in your hair's appearance and scalp health. Our Organic Herbal Scalp Revitalizer Oil, rich in plant-derived active ingredients, vitamins, and fatty acids, nurtures a healthier scalp environment, reducing inflammation and tenderness, potentially resulting in fuller, thicker, stronger, and faster-growing hair.
