Frequently Asked Questions

We recommend using our 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.

No. Our lightweight, non-greasy Scalp Serum is water-based, so it doesn't leave any oily residue behind.

We recognize that some users have more sensitive scalps than others. You will still have the same benefits of applying our Scalp Serum whether there is a tingly feeling or not. Some users report a more pronounced tingly feeling if they use the serum immediately after showering on clean, damp hair, so that may be worth a try!

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.

    It's a big in just two weeks. My hair feels a little bit thicker. And the shedding has definitely subsided noticeably, which is great. So i'm very hopeful as I continue to use this product

    I was doubtful

    I had tried all kinds of different things for my hair loss and horrible shedding. With hypothyroid, glp1, and menopause I couldn’t get it under control until I found Divi. OMG I’m 3 months in and the regrowth is filling in those thinning areas and my hair is fuller. Nothing else gave me great results. It’s water based so it doesn’t have that oily feel. It will always be a part of my nighttime routine!!
