Ruined my hair. I had beautiful thick hair and not its stringy and dull. Honestly I’m so sad I have my wedding in the next 6 months and not sure what to do.

Really regret not reading this reviews before buying. I have been having keratin treatments for a long time at home and in salons. I decided to try the best.well it’s not the best. My hair turned an orange colour Before I had applied any heat and super static after. I have had my colour change slightly but not to this level. And the static I have never experienced. I have had to apply a semi permanent and apply a gel cream, even though it’s not recommended after. But had no choice. My advice. Don’t waste your money. Am really worried about the longer term damage after. It has clearly dehydrated my hair. The other thing I found odd was that all bottles except the actual treatment had a seal.

Terrible customer service! Sent me a half empty, partially dried up bottle of conditioner. Their solution was to replace it "when I order from them again". Not NOW, when they already got paid for it! Ridiculous and unprofessional! Never order from them! In reading older reviews, they had great consistent customer service until recently. I'm wondering if they've been sold? It seems like they use a outsourced phone reps now. It would explain a lot. They did, finally send me a replacement bottle but I'm still done with this company. I don't trust them anymore! Too many other options!

I had an absolutely terrible experience with GK Hair. I purchased their keratin product, expecting quality, but was left completely disappointed. When I realized the product wasn’t what I expected, I tried to return it, only to find out that they don’t even provide a return label. I followed up with them for two months, and despite multiple attempts, they never processed my refund. Their customer service is beyond awful, unresponsive, and completely unhelpful. It’s clear they have no standards or accountability. This company thrives on fake hype and paid promotions, tricking customers into buying overpriced products that don’t seem genuine. They target people’s weak points with big claims, but in reality, the experience is nothing but frustration. I strongly recommend avoiding GK Hair at all costs. Save yourself the headache, and don’t waste your money on a company that doesn’t care about its customers.

My 4th time doing GK The Best was on 8th dec 2024 in Bogota airport El Dorado Hairdressers. I used to LOVE IT. Normally freeze was gone, but not this time. On 27dec, they repeated the treatment as good-will gesture. This time, freeze reduced a bit, mostly on the roots but the ends of my hair ended up straight (instead of wavy) and steel freeze from the middle lenght. I noticed the product smelled milder. I wonder if GK changed composition or the hairdresser are mixing products or not using enough. Unfortunately I am disappointed and confused. Im using all GK after treatment care: shampoo, conditioner, deep conditioning masque, leave in spray, and the serum. This is a call to GK to check on their distributors (?) or formula (?) and a call to me to find a new trusted haircare brand.

Best hair products I have ever used! I have been using the GK Hair products since 2010. I started with the Smoothing Treatments, like Resistant and The Best now, which is my favorite for smoothing my hair and making it more manageable. My go to products to use at home are the Shield Shampoo and Conditioner, Serum, Leave in Conditioner Spray, and Leave in Conditioner Cream! I am not coloring my hair at the moment, but when I was I also had the GK Hair color line applied on my hair and absolutely loved the results!

I have been using this product for years, and contacted customer service about a problem with the formulation of my most recent shampoo order, which was weirdly oily. I asked for an exchange or refund. They requested photos of the container, a video showing the consistency of the product, and after all that over almost a month, they have have done nothing to resolve the problem. After over 10 years of using this product, I will move to an alternative. Incredibly disappointing...

Horrible customer service! It took them ages to finally take my complaint into consideration and when they finally did agents keep changing after every email and each one asked for something different. When they finally offered me store credit and I accepted, they never emailed me back to let me know how I can use it!!!! I am still struggling with them after weeks of buying the product which was not good at all. Worst experience I've ever had with customer service in my entire life.
