Known to reduce and prevent excess oil buildup on the scalp and in the hair follicle.

Amino Acids
Support hair strength, fight frizz and reduce the effects of breakage for overall hair health.

Nourishes and hydrates the scalp for a clean environment for healthy hair.

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.

    Works great

    I started using this about 4 months ago. I can see the new hairs growing back and overall my hair seems to be growing at a faster rate than before use. This product is definitely better than other hair growth serums I have used in the past.

    Really works to strengthen hair and replenish scalp!

    I have been using this product to combat shedding due to perimenopause, and I can honestly say that I see a noticeable difference in the health of my scalp and the thickness of my hair overall. Would absolutely recommend this product to friends!

    Scalp serum

    I love this product! I have used for years. I’ve struggled with hair loss off and on due to stress and medications. This serum makes a difference from keeping my scalp healthy to new growth.

    Loving it!

    So far, so good! Makes my scalp feel clean, and I love that it is water-based rather than oil. Using it every night and excited to see the results.
