[@beckythepooh]

I think I’m sold. Working on my self care and step 1 is skin and hair! Your hair is goals! I also need the shower head filter you recommended🤑

So helpful. I was really wondering how this mask works. Thank you, much appreciated!

[@michellebragg4975]

I love how educational this is ❤

[@rbee23]

It was your original Instagram post on this product that had me trying this at the last Sephora sale and I’ve never looked back. Love this product and I have gotten at least 4 other friends to try it!

[@amanb7728]

I bought this because so many people were raving about it! When I went to use it I was lost, but thankfully Amy K always to the rescue! Thank you for your videos they always help

[@briannaschardien6525]

This was so informative! Thank you ❤

[@bballblonde25]

I just bought this on your recommendation! Can’t wait to try- I’m 6 months postpartum and trying to get my hair loss under control lol

[@reshmapatel23]

I’ve always wondered if this was as good as everyone made it seem. I’m going to buy some and try it out now!

[@jensullivan428]

Wow thanks so much. This was so helpful for hair care!!

[@AmberMueller-dx7fh]

Thank you for always sharing your insightful feedback & information on products 🤍 I’ve always wanted to try K18, so hearing your review/perspective makes me want to finally purchase 🙏🏼 You’re the best!

[@Swilson9915]

This is helpful. Thank you for the information 🎉

[@ashleynguyen6094]

Loved this!! It would be awesome if you could talk about Olaplex products in a future video!!

[@AnnaH-ut7bw]

Thanks for sharing- so helpful!

[@brittanysykes7994]

Thank you, very informative! I often overlook my hair 🫣

[@aileeenvento7606]

Love this video & your content!!! Thank you so much!!

[@aneyedr]

Thank you for this informative video! K-18 is a great product. I used it 6 consecutive washes before I noticed a 90% improvement from breakage from daily heat styling with a curling iron. Now I maintain with twice a week usage. Please keep these awesome videos coming!

[@Kenhood22]

Love your content!!

[@ToshaHardman-rg3eq]

Love your videos and posts about skincare 🩷

[@user-rq4nm3ur6o]

Love this info!

[@susanmcmackin5865]

I want to try this, but so far I've not wanted to spend the money. Your explanation of how far a little product goes, I'm reconsidering! Thanks for the information 👍

[@Maddisiket]

One of my favorite hair products that I’ve tried bc of you! Also got the k18 oil but noticed more of a different with this product

[@allegraliedtke6250]

Thank you for explaining!

[@jordanmandell3035]

So helpful! Thank you

[@Rachel_AllThingsFoster]

I used k18 for the first time tonight and I was very impressed! Can’t wait to continue to use it and see more results!

[@AmyKoberling]

so glad to hear that

[@ChloeCarver-nw1ro]

Loved this concise breakdown! I notice that your hair is fairly straight/light waves, is this product also effective for hair that is on the curlier side as well?

[@anaderiba3971]

Your hair looks amazing! I'm sold😂❤

[@mzvivian]

Really want to try this!

[@jackiem.259]

Wow this was super informative. I followed the instructions and didn’t condition but I did probably use too much. I’m going to warm it up in my hands then apply to my hair. Good tips 😊

[@MelissaFreeman]

I just ordered mine and can’t wait to try it

[@koll13_]

Ive been watching Abby yung for a long time and shes always preached K18, I've loved it so far! (Also i will prob start watching you videos as well because honestly they seem really good)

[@NicoleK-ez2yc]

Super informative- have been holding off on buying this due to the price tag but now very eager to try. Have heard mixed reviews about not using conditioner with it but good to know you can after 4 minutes

[@ally_cabre]

I've bought this! Will use all your tips

[@AmyKoberling]

can't wait to hear what you think!

[@MarisolGarcia-rr8wg]

This is definitely something I should try…bayalage and daily heat damage.😬 Thank you for the info!

[@betabree]

Thanks for the helpful video. I went through an entire bottle and didn't notice much difference in my (thin, fine, not processed) hair. Thinking now I need to give it another go...

[@lisazver8517]

Thank you for explaining. I was shocked when I used the product with no conditioner and how it softened and detangled my hair after 4 mins. Plus they sell a mini version if you want to test out before.

[@tarynmarquis1180]

Thank you for taking the time to go so in depth on this explanation! The tip about really working it in your hands first is so helpful!

[@ally_cabre]

Just bought k18 mask and hair oil! Cant wait to use it using your advice

[@AmyKoberling]

I can’t wait to hear what you think! They’ve changed my hair!

[@bleakbutterfly]

Love your content. How does this compare to Briogeo Deep Conditioning Mask and Strengthening Treatment Oil? Thanks!

[@user-vv7uj9ii2p]

Just ordered some k18 products to try!

[@mariahmeasey3220]

As a recently postpartum mom, this has been SO helpful! I’m losing hair and looking for all the help I can get so I really hope this product can help with smoothing my coarser hair! Thanks for the educational breakdown :)

[@AmyKoberling]

PP hair thinning can be so frustrating! Know that it’s a part of the process and it’s self limiting!

[@alito238]

@@AmyKoberling Can we use Olaplex three before shampooing and K18 after shampoo?

[@AmyKoberling]

@@alito238 you don’t want to put any product on the hair before k18. Plus k18 actually repairs both the keratin and polypeptide chains so you don’t really need a second bond builder

[@pamw3238]

​@@AmyKoberlingcan I just use my normal aveda shampoo instead of a clarifying one?

[@brittanymarano5769]

I need to try K18! I bought it for my mom who dyes her hair regularly, but think this would help my hair since I get balayage. Love your Instagram account and just subscribed to your KZbin channel.

[@LightingJedi]

Thank you for explaining and I just tried it through my lovely hair dresser who put it on my ends which have been bleached and straightened and menopause hasn’t helped at all but I can’t recall which one she used she washed my hair and then added the K18 two pumps I think it was over my dried mid length to ends & immediately after drying I’ve noticed a huge difference in one week not washing and it’s not as frizzy or dry it actually has a shine the tangles weren’t as bad so something significant has definitely happened

[@FSchmidt13]

Thank you!! Very helpful! Do you ever use conditioner after the mask?

[@AmyKoberling]

I personally don’t! But the brand has said you can as long as you wait 4 minutes before applying

[@mishu70]

👏 👏 Thank you!

[@user-sq8jh2rg8x]

Love this product 🎉

[@kaylasheneman4485]

I’ve just recently started getting my hair professionally colored, and cut regularly (once a year 🤦🏻‍♀️). I feel like the closer I get to months 8-10 😬 before getting it done again, the more dry and problematic my hair gets. I’ll definitely give this product a try, maybe seeing if I can stretch getting it done again for another month or two

[@dob8240]

Did it work for you?

[@hughesm8]

I need this!! Post partum hair is rough😅

[@ladygeo5285]

what about for hair thinning.. will it help?

[@sumanthhi4585]

Ok I started using it,first thing keep expectations right, It will work for sure but I expected a miracle which is not the case here. But it works after 2 uses definitely some 20-30% repair is there for sure, applying it for thick hair is little hard.

[@sammie2537]

My hair is relaxed and I would straighten every single day on 450. Never in my life did I think I could go a day without using a straightener but I only straighten every 3/4 days on 375 and it stays like that for days. I’m extremely happy with k18 and I get out of the door so much faster because of it!

[@saminarahman9870]

Sorry if I have misunderstood that for this mask to work in full efficacy, it is imperative to use its own brands shampoo?

[@AmyKoberling]

definitely not! I do recommend a clarifying shampoo before the mask and their's happens to be my favorite but you absolutely do not have to use their shampoo!

[@braleepichaiya5973]

I started using K18 for 2 times now. My hair is so silky and has more weight. Will continue to see the full result.

[@honeydubey7119]

Can you please reply.. it says apply from roots to ends So , have you applied this product into your scalp too ??? Please reply

[@enderselcuk9925]

Hi, Can we use a rinse off conditioner after applying K18 and waiting for 4 minutes.

[@AmyKoberling]

Yes! You apply the k18, wait 4 minutes then you can condition and rinse out according to the brand!

[@yogaqueen515]

I had a difficulty with K18 mask application without using hair conditioner or mask beforehand . I tried to use it 8 times and gave up . I guess it’s not for over processed hair 😢

[@Sara.H.T]

Can i use a styling cream or serum after?

[@AmyKoberling]

Yes! Just wait 4 minutes after applying the k18
