Best growth product I've found in 20 years

"I've tried TONS of products and this is the first affordable product that is changing my hair. So happy!"

— Kate B. (5/5)

Really works!

"I was skeptical but I've noticed such a difference after only a few weeks! My hair feels fuller and also very soft."

— Morgan N. (5/5)

Easy to apply

"Very easy to apply with the suction dropper thing. Smells good but not too strong and it doesn’t leave my hair greasy looking at all. Time will tell if it actually makes my hair thicker. I’ve only been using it two weeks."

— Laura G. (4/5)

Hair Growth

"I’ve been using the Density Peptide Hair Serum for about two months and I’ve definitely seen a difference in the thickness of my hair. Great product."

— Michael K. (5/5)

The best!

"Being postpartum this has made my hair feel and look so much better!"

— Madison Z. (5/5)

Loving it so far

"I haven’t been using the product long enough to see real results, but I can say my shedding has reduced and I absolutely LOVE the smell of this! I do wish the bottle was bigger or the price was a little lower for the amount you get but if it works I’ll figure out a way to budget it to save my hair."

— Rachel C. (4/5)

As a 65 year old

"As a 65 year old male, I have some thinning hair areas. Tried this and saw immediate improvement. Hair now has nicer wave and body to it, and it seems to cover the bare areas a bit better. I will definitely continue to use. . . great product."

— Bill P. (5/5)

2nd Time Buying

"I love it and it works so well my husband started using it (and has used it all up) so we are on round two."

— Molly D. (5/5)

will these products make my hair greasy or weigh it down?

no. both formulas are lightweight, silicone-free and water-based, designed to visibly improve fullness without buildup or heaviness. the density peptide hair serum was specifically created to be non-greasy and absorb easily into the scalp.

is this safe for color-treated hair?

verb is committed to formulating all products without SLS or SLES, two harmful sulfates that are known to strip hair of color. if you have concerns about color fading, please consult with your stylist.

do these formulas have a fragrance?

the density peptide collection has an uplifting, herbal scent with notes of bergamot, sage, rosemary and lavender, made with a blend of essential oils.

can I use these products with other verb products?

how long does a bottle of the hair serum last?

it can vary from person to person. when applying the serum daily as a spot treatment on areas of concern, one bottle should last approximately 1-2 months.

can I use the shampoo without the serum (or vice versa)?

for best results, we recommend using both as part of a consistent routine.

how can I improve my hair density?

you can support hair density by building a consistent routine focused on scalp care, hydration and a balanced diet. using products like our density peptide hair serum and shampoo can also help reduce visible signs of shedding and improve the look of fuller hair over time.

how do I check my hair density?

there are three types of hair density: low, medium and high. to check your hair density, part your hair and see how much scalp shows, do a ponytail test with a measuring tape or run your hands through dry roots to feel fullness. knowing your density helps you choose the right products and techniques.

can thin hair be thick again?

you can’t create more follicles, but with the right routine and ingredients, thin hair can appear thicker. products designed to support hair density, like our density shampoo and hair serum, help reduce the look of thinning hair and add visible fullness.
