Easy to order, nice stuff

I needed some new shampoo so I grabbed the Shield Shampoo and Conditioner. The website was super easy to use, no fuss finding what I wanted. It got here pretty fast, and my hair feels good after using it. Not too heavy, just clean and soft. Would probably order again when I run out.

Value for money on a bundle

I was looking for a good deal and found one of their Hair Care Bundles. It included the Balancing Shampoo, Balancing Conditioner, and a Leave-In Conditioner Spray, all at a decent price. I signed up for the newsletter and got an extra 10% off my first order, which definitely made it feel like a smart purchase. For what I paid, the value was definitely there. I'm happy with how my hair feels, and it didn't break the bank.

Consistently great results

This isn't my first time ordering from GK Hair AU. I've bought the Serum with Argan Oil multiple times now, and it always delivers. My hair tends to get frizzy, but this serum really helps keep it smooth without feeling greasy. Shipping was again reliable; it arrived within a week, just like my previous orders. Glad to see the quality and service are consistent.

Quick delivery, good product

Ordered the ThermalStyleHer Cream. Arrived in 4 days. Product works well for heat styling. No issues.

Good products, shipping could improve

I ordered the Moisturizing Shampoo and Conditioner. The products themselves are really nice, my hair felt soft and looked shiny after using them. The packaging was secure, no leaks or anything. However, shipping took 8 days to reach Melbourne, which felt a bit slow compared to other online stores I use. It's not a deal-breaker, but something to consider if you need items quickly.

Hey guys, wondering if anyone knows how long shipping usually takes for GK Hair to Melbourne? Need to restock my conditioner soon!

J June 2 months ago

Mine usually takes about 3-5 business days to Sydney, so Melbourne should be pretty similar, I reckon.

P Phil Nguyen 2 months ago

Yeah, I'm in Adelaide and it's usually quick, like under a week. They ship from NSW from what I remember.

Is GK Hair the same as Global Keratin? I see both names around and just want to make sure I'm buying the real deal from the official site.

P Phil Marsh 2 months ago

Yeah, GK Hair AU is like, the official Australian site for Global Keratin. So you're getting the legit stuff.

They are the official ones in Australia, so you're good. Don't worry about fakes if you buy from their site.

Any tips on getting a discount? Planning a big order for a few products and hoping to save a bit.

R Renee 2 months ago

Sign up for their newsletter, usually get a first order discount code pop up. Or check if there's an Afterpay Day sale on soon.

I usually wait for their Black Friday or Boxing Day sales, those are the best for bundles. Sometimes they have 10-15% off codes if you search around too.

Thinking of trying GK Hair's keratin treatment at home. Does anyone know if it's safe for coloured hair? Don't want to mess up my fresh highlights.

J Jared D. 2 months ago

Yup, totally fine! I use it and my hair is bleached and coloured. Doesn't strip it or anything.

M Marcus 2 months ago

My stylist actually recommended it because it's supposed to be good for colour-treated hair. Never had an issue with fading.

How do GK Hair products compare to Olaplex? My hair is super damaged and I'm trying to decide which line to commit to for repair.

P Phil S. 1 month ago

Olaplex is more for bonding and repair from inside, GK is more about smoothing and the Juvexin helps with frizz and strength. I use both actually, but for different things.

I switched from Olaplex to GK Hair a while ago, and I prefer GK for the overall feel and smoothness, especially their treatments. Olaplex is great, but GK just makes my hair feel 'healthier' if that makes sense.

Anyone successfully returned something to GK Hair AU? My hair didn't like the serum and I'm wondering if it's a huge hassle.

A Alex 2 months ago

Yeah returns were easy, did it last month. Just had to fill out a form or something and send it back.

I returned a shampoo once that irritated my scalp. It wasn't too bad, they processed it fairly quickly after they received it. Just make sure you follow their instructions on the website.
