Trustpilot review
“I didn’t expect my hair to change this much.”

When I went through menopause, my hair started feeling thinner. I kept buying different shampoos… lately my hair has felt more manageable and looked fuller.

“I’d recommend it.”

Would recommend this product to all mid-age women experiencing scalp hair loss!

“I felt silly for crying about my hair.”

There was already so much changing with menopause. Then my hair started thinning too, and that was the thing that made me cry one morning. I’m seeing less shedding with Boon now.

“My husband said he couldn’t tell.”

But I could tell. I knew how thick my ponytail used to be. With Boon, I’m starting to notice a difference myself. That means more to me than someone saying it looks fine.

“I almost deleted the photo.”

My daughter sent me a picture of us at lunch and all I could look at was my scalp. I’ve noticed it looking fuller since starting Boon. I want more pictures with her.

“My ponytail was getting so thin.”

I noticed I was wrapping my hair tie around an extra time… I’ve gradually noticed my ponytail feeling fuller. I’m glad I took photos at the beginning.

Questions

The details, covered

What if it does nothing for me?

Every order comes with our 90-Day Satisfaction Guarantee. Use it every day, and if you’re not happy with it within 90 days, email hello@theboonlabs.com and we’ll refund your order.

Will it leave my roots greasy?

No. It is water-based and clear, not an oil. One dropper absorbs in seconds and leaves no film.

Is it safe on color-treated and gray hair?

Yes. No warmth, no brassiness, no interference with a gloss or a toner. It sits on the scalp, not on the strand.

How long does one bottle last?

30 days at one dropper a day. The dropper is graduated so you can see how much you use.

Can I use it with minoxidil or my other products?

It layers under any styling product. If you use a medicated treatment, ask the prescriber before adding anything to the same scalp. It contains no minoxidil.

Who is it not for?

Postpartum shedding, alopecia areata, hair loss under active medical treatment, or anyone under 35. Pregnant or nursing? Check with your doctor first.

What if it irritates my scalp?

Stop using it and email us at hello@theboonlabs.com. We’ll make it right. Patch test behind the ear first if your skin is reactive.
