Loved the Hair Gain Extract!

I just got my Hair Gain Extract and I'm already seeing such a difference. I'm so happy with it! My hair feels thicker and healthier. Definitely shopping here again!

Got the Travel Set, pretty good

I snagged one of their Travel Sets to try a few things out. It was a nice way to sample the range without committing to full-size bottles. Everything smelled good and worked well for my hair. No complaints, it was a smooth experience start to finish.

Detailed thoughts on my order

I placed an order for the Hair Growth Kit and added a Scalp Brush. The ordering process on their website was straightforward and easy to navigate. I received an order confirmation email promptly, which was reassuring. Shipping took about 6 business days to arrive in California, and the package was well-packed with no damage to the products. I've been using the kit for a few weeks now. The Cleansing Shampoo and Hydrating Shampoo both feel gentle and don't strip my hair. The Hair Gain Extract applies easily, and the Scalp Brush is surprisingly effective for massaging the scalp. I haven't needed customer support, so I can't comment on that, but so far, the quality of the products seems high. The instructions included were clear, helping me integrate everything into my routine. I'm optimistic about seeing long-term results.

Decent products, slow shipping

I ordered the Balancing Shampoo and Daily Conditioner. The products themselves are quite good, left my hair feeling clean and soft without being too heavy. My only gripe was the shipping time; it took about 8 days to get to me in Florida, which felt a bit long. Customer service was polite when I inquired, but still, a little patience was needed. Overall, I'm satisfied with the quality for the price.

Good value for a kit

I was looking for something to help with my hair thinning and decided to try the Postpartum Hair Kit. It felt like a good deal compared to buying everything separately. The products seem to be working, and I appreciate the bundle savings. Worth the purchase for sure.

what's the deal with returns if the products just don't work for me? kinda worried about dropping a lot of cash.

O Omar 3 months ago

I returned some stuff once that didn't agree with my scalp. It was pretty straightforward, just follow their return process on the website. I think you have 30 days.

They have a return policy. As long as it's within their timeframe and you follow the instructions, you should be fine. I haven't had to do it myself but I've heard it's not a hassle.

Does Harklinikken actually offer free shipping? Their stuff is kinda pricey already, trying to save where I can.

C Cody Foster 2 months ago

They do! You usually get free shipping if your order is over $100. Most of their kits or a couple products will hit that.

S Shane 2 months ago

Yep, over a hundred bucks gets you free shipping. Pretty standard these days for online stores.

Can I stack a first-time buyer discount with a holiday sale code at Harklinikken? Trying to maximize savings.

M Megan Vargas 2 months ago

Nah, usually you can only use one code at a time. I tried to do that during Black Friday and it wouldn't let me.

From what I remember when I ordered, their system only takes one promo code per order. So pick the better discount!

hey, was thinking about trying the Hair Gain Extract. Anyone know if it's safe for colored hair? I just dyed mine and don't want it stripping the color out.

E Emma 2 months ago

Yeah, totally fine. I use it and have highlights, no issues at all. Doesn't mess with the color.

My stylist actually recommended it to me even with my balayage. It's supposed to be gentle enough, doesn't contain harsh sulfates or anything that would strip it.

Thinking of signing up for their newsletter, does Harklinikken give you a discount for your first order then?

M Mike 2 months ago

Yep, usually you get a welcome code for signing up. It's typically 10-15% off, I think.

They usually send you a code for a percentage off, worth doing for sure if you're planning to buy something anyway.
