Niamh Osei –
Hey Unihairvn, can you pre-tone the hair to a cool ash tone before shipping?
Unihairvn –
Hi Niamh, yes we can custom-process to #613 or piano. Lead time is 10–14 days because we process in-house. WhatsApp for a color-processed quote.
Scarlett Zhao –
Can you confirm the hair isn’t synthetic-blended? My salon clients color-process everything.
Unihairvn –
Hi Scarlett, our raw hair handles heat styling up to 400°F without damage because the cuticles are intact. Flat iron, curling wand, blow-dryer — all safe. DM WhatsApp if you want our heat-styling care guide.
Deirdre Lopez (verified owner) –
After trying multiple vendors, I’m sticking with Unihairvn. The natural texture blends with virgin hair after installation. Easy to install — bonds melt evenly with the right heat tool. I compared it side-by-side with my previous vendor — Unihairvn wins. Thank you for the fast WhatsApp response too.

Pauline Harris (verified owner) –
I was skeptical at first but this exceeded my expectations. Hair quality at the bond is as good as the mid-shaft. 22 inch length gives my clients fullness without over-weight. Each piece weighs exactly 100g as promised. Quality + price + service = winner.

Can’t say enough good things about this. The natural texture blends with virgin hair after installation. 26 inch length gives my clients fullness without over-weight. If you’re on the fence, just order a sample.

Switched from a Chinese vendor and never looking back. No breakage at the bond even after months of wear. Nano ring tips are the smallest I’ve worked with — nearly invisible. Ordering again this week.

This is my 3rd order from Unihairvn and still consistent. No breakage at the bond even after months of wear. Flat tips lay flatter under rows than traditional round tips. Took bleach to #30 with no breakage. Thank you Unihairvn team — see you on my next invoice.

Honest review from a dropshipper. I-tip strands are uniform, no fraying on any piece. No breakage at the bond even after months of wear. Hair survived my blowout without any damage. Quality + price + service = winner.

Not my first order and definitely not my last. I-tip strands are uniform, no fraying on any piece. V-tip bonds held for 3 months without slipping. Factory-direct really does make a difference.
