Frequently Asked Questions

HOW OFTEN SHOULD I APPLY THE SERUM, AND HOW MUCH SHOULD I USE?

This serum is designed for once daily use. Most users find that 3 to 4 pre-measured droppers per application works well to cover the full scalp.

HOW SOON UNTIL I SEE RESULTS?

In our consumer study, 70% of users noticed visible results by week 4, and that number climbed to 96% of users by week 12.

WILL THIS PRODUCT MAKE MY HAIR GREASY OR OILY?

No — and we were so intentional about that. This was especially personal to Blair. During her own hair journey, she found that nearly every product left her hair greasy or made her feel like she had to wash more — and anyone who’s been there knows the heartbreak of watching more hair fall out with every rinse or brush. That’s why creating a formula that eases stress, not adds to it, was non-negotiable from the start.

WHAT HAPPENS IF I STOP USING IT?

While continued use helps maintain your best results, stopping has not been shown to cause any negative rebound effects.

IS THIS SAFE FOR COLOR-TREATED OR CHEMICALLY TREATED HAIR?

Yes — our serum is safe for all hair types, including color-treated, highlighted, and chemically processed hair. It’s gentle, non-stripping, and carefully formulated to support scalp and hair health without compromising your treated hair.

CAN I USE THIS WITH OTHER HAIR GROWTH PRODUCTS OR TREATMENTS?

Yes — you can safely use this alongside other hair growth products, including topical or oral minoxidil. We recommend adding in new products one at a time so you can see how your scalp and hair respond. If you’re using prescription treatments or have any concerns, it’s always a good idea to check with your dermatologist or healthcare provider.

IS THIS SAFE TO USE DURING PREGNANCY OR WHILE BREASTFEEDING?

We understand how challenging hair changes during pregnancy and postpartum can be. While the serum is designed to be gentle and supportive, we always recommend consulting your doctor first to make sure it’s right for you during this special time.

The dropper doesn’t fill completely, is this expected?

Yes! Our droppers are designed to fill about a third of the way full. This is intentional and pre-measured so you get the perfect amount. For best results, use 3–5 pre-measured droppers to cover the full scalp.

SHOULD I USE ON WET OR DRY HAIR?

You can apply Scalp Serum on wet or dry hair. If applying to wet hair, allow it to air dry naturally. It is best not to use heat styling or blow-drying immediately after application.

    Love this non-greasy serum!

    I have been using this scalp serum for about a month and love the feel so far! It's non-greasy which has been a game-changer for my already oily hair. The dropper is a little different than some of the other serums I have used. I was honestly nervous about it at first, but it is actually wonderful! I love that it is already pre-measured so I get the exact amount and am not wasting or overusing given the higher price point. It also glides along the scalp which I feel like helps distribute it across my scalp.

    Loving it so far!

    I ordered this hair serum immediately after it launched as I’ve been looking forward to trying it. I love how it does not make your hair greasy at all and it smells great! I can’t speak to hair growth yet since I’ve only been using it for a few weeks. However, I trust everything Blair creates and I know I can only expect great things to come from this serum. Thank you, Blair for creating yet another top tier product to add to my shelf!

    Deep exhale to have this product

    My scalp serum is a daily non-negotiable now, another Blair product I can’t go without. I’ve applied every single day and cannot wait to see results over time. I appreciate how well this blends into my hair and doesn’t make it look or feel greasy. Dare I say it almost gives it immediate volume?
