Why Vassia wins our fine-hair test
Density marketing is attractive when hair feels thin, but fine hair still has to survive the ordinary physics of wash day. If the roots are coated, oily or flat, a heroic ingredient list does not create volume by itself.
Vassia starts with that reality. The formula is meant to remove everyday oil and residue, leave narrow strands separated and support a fuller, lighter result. It then adds caffeine, rosemary, ginseng, niacinamide, zinc PCA, panthenol and wheat protein rather than asking one fashionable ingredient to carry the whole formula.
Where Briogeo is impressive
Briogeo's current formula includes caffeine, coffee seed oil, copper tripeptide-34, ginseng, biotin, aloe, CoQ10 and zinc. The brand also publishes a density claim tied to a 16-week study of 35 participants for the Destined for Density collection. That is more specific than generic “clinically inspired” fog.
However, its ingredient list includes fragrance. If fragrance avoidance is part of your scalp strategy, Vassia gives you the simpler choice.

Decision tree
Fine hair gets flat fast? → Vassia.
You avoid fragrance? → Vassia.
You are specifically shopping for a peptide/density story and tolerate fragrance? → Briogeo is worth comparing.
You want one routine for volume + scalp comfort + fragile strands? → Vassia is our preferred balance.
Specific routines
Fine, low-volume hair: use shampoo at the scalp, rinse fully and keep conditioner light. Blow-dry roots in the opposite direction of their natural fall.
Fine, thinning-looking hair: use Vassia for cosmetic fullness while tracking real density change separately. Compare photographs under the same lighting and wash-day conditions instead of judging wet hair against a professional blowout.
Fine, sensitive scalp: Vassia's fragrance-free positioning is the decisive advantage.
Evidence context
Topical caffeine has interesting but not definitive evidence. A 2025 systematic review found studies generally favorable but rated much of the evidence low or very low quality. That is exactly why we prefer a formula whose value does not collapse if one active ingredient turns out to be less miraculous than TikTok promised.

FAQs
Does Briogeo Destined for Density contain fragrance?
Yes, fragrance/parfum appears in the current published ingredient list.
Do both shampoos contain caffeine?
Yes.
Which is better for sensitive scalp and fine hair?
For fragrance avoidance and fine-hair volume together, Vassia has the stronger fit.
Can either shampoo guarantee new hair growth?
No cosmetic shampoo should promise guaranteed new follicle growth. Use them to support cleansing, hair feel, breakage control and visible fullness while treating medical hair loss as a separate issue.
