FAQs

How soon will I see results with QUABROW®?


Most users report visible improvements in brow fullness and density within 4 to 6 weeks, with optimal results achieved after 8 to 10 weeks of consistent use.

What kind of results can I expect?

- 94% saw fuller brows
- 88% noticed improved brow shape
- 98% observed better definition and thickness

Results based on self-assessment after 8 weeks of regular use.

Why is QUABROW® so effective?

Its power lies in the QUA-X Complex™ – an advanced formula with multi-action peptides and botanical extracts that nourish brows from the root, stimulate growth, and strengthen each hair over time.

Is QUABROW® safe for sensitive skin?

Yes. The formula is dermatologist-tested, fragrance-free, and free from prostaglandins or harsh chemicals – making it suitable for sensitive skin and daily use.

How do I apply QUABROW® correctly?

Apply once daily to clean, dry skin. Use the applicator to trace the shape of each brow. Let the serum absorb fully before applying any makeup or skincare.

Can I use QUABROW® with brow makeup or tinting?

Absolutely. QUABROW® works great alongside makeup, brow gels, tints, or even after microblading. Just apply the serum to clean skin before anything else.

What happens if I stop using QUABROW®?

Your brows will gradually return to their natural growth cycle, but you won’t experience hair loss or sudden thinning. Continued use supports long-term results.

How long does one tube (3.5 ml) last?

One 3.5 ml tube of QUABROW® lasts approximately 4 to 5 months with daily use.

Most other brow serums offer only 1–2 ml for the same price. With QUABROW®, you get more product, more results, and more value.

Has QUABROW® been clinically tested?

Yes. QUABROW® is inspired by research on peptide-driven hair stimulation and is powered by our proprietary QUA-X Complex™.
