  • We recommend using Divi's Scalp Serum daily for 3 continuous months to see best results. That said, you may experience benefits after just a few uses including a happy scalp, more hydration and less product buildup.

  • Some users have more sensitive scalps than others. You’ll get the same benefits from our scalp serum with or without the tingly feeling. Tingling may feel stronger when applied right after showering to clean, damp hair.

  • If you notice any unusual symptoms, stop using the product immediately and consult your doctor.

  • Yes! Our Scalp Serum is designed to fit into your normal hair maintenance and styling routine.

  • Our Scalp serum is good for those with itchy, dry scalps, those with hair shedding/thinning, scalps with a lot of product or oil buildup, those who wear tight hairstyles, those with extensions, and anyone looking to start a cleansing scalp routine.

    This stuff is amazing and it is working wonders for my scalp! I have menopausal hair loss and I am allergic to minoxidil. This serum grills so good and is so easy to use. Didn't think it would work, but I have noticed significant hair growth in the kids areas after just one bottle. Still need more growth to fill in the spots of loss, but really love this serum!

    Started using 2 months ago. Went to my hair appointment and my beautician said "you hair feels thicker, what have you been doing". I showed her a picture and told I lived how it made my hair feel but was positive it was working but she confirmed it was and to keep using it. She also asked I send her a picture of the bottle.

    4.0 out of 5 stars Not bad
    Reviewed in the United States on June 5, 2025
    Style: 30 ml - 1 Month SupplyVerified Purchase
    I am always very skeptical of any hair serum that says it helps with thickness. However, the reviews on this product seemed promising so I decided to buy it. I went through the first bottle and didn’t really notice a difference but that was to be expected since it says it takes about 6 weeks to see a difference. I’d say one bottle got me right to that 6 week mark. A week after I ran out, I noticed it was on sale so I decided to buy another bottle. I am now on my third bottle and have definitely noticed a difference. Whether it is actually making my hair thicker or just making it appear that it is thicker I’m not sure. But I am happy with the results because I feel that it looks fuller. I will say, I only buy it when it is on sale which is seems to be quite often so I’ve been able to consistently buy it. However, if it was always at full price I’d probably do without it. I will also note that it seems to work better when you put it on wet roots. I can feel it tingle when I use it right after I wash my hair but on non hair wash days I don’t feel it tingle on a dry scalp. The tingle is very mild, not painful at all.

    I’ve been using this serum for thinning hair for a few weeks now, and I’m already starting to see some positive changes. My hair feels stronger, and I’ve noticed less shedding, especially when brushing or washing. The serum is lightweight and non-greasy, so it doesn’t weigh my hair down or make my scalp feel oily.

    It’s easy to apply—just a few drops massaged into the scalp—and it absorbs quickly. I appreciate that it has a mild, pleasant scent and doesn’t irritate my skin. With consistent use, I’m hopeful for continued results. So far, it’s been a great addition to my hair care routine, and I’d recommend it to anyone dealing with early signs of thinning.

    I used this serum for a month to try to help some postpartum hair loss. I love the smell and like that it did not make my hair greasy. I have tried scalp oils which always left my hair feeling greasy but this did not do that. I used it every day for a month and didn’t notice a difference but I know the claims are for longer use. I didn’t want to continue to pay for it but may try it again in the future. I had no adverse reactions to it and think it is a nice addition to your hair care routine if you are willing to pay for it.
