Instant Detangling

My hair felt amazing. I can't get over how the oil immediately detangles. I literally run it through my hair and the brush goes through straight away.

Amazing

I absolutely love the hair oil, it has become essential for me now, I can’t rinse my hair with just water anymore without applying the oil afterwards. It leaves my hair feeling incredibly soft, silky, and perfectly defined with such a nice natural curl. Not greasy at all !! My hair also feels much healthier and smoother overall. The oil really feels like silk and the smell is incredible. every time I hug someone, they always compliment it!!
Thank you again for all the mermaid 🫶🏽✨
Honestly, you can truly feel all the love and quality behind your products, and it really makes a difference.

Such a noticeable difference for my dry hair

The Hair Serum was incredible. I’d been going through a really dry period with my hair, and there was a noticeable difference after using it — my hair was so soft. When I was in Caribbean, I really lathered it in, and it helped my hair bounce back so much faster after long days in the salt water.

My New Daily Moisturizer

This water cream became my new daily moisturizer! I’m very very picky with my face creams and love this one! My makeup applied really well over this cream as well.

Finally able to comb through my hair after ocean days!

Honestly the whole range is incredible, but the hair serum especially blew me away. The smell is to die for, and I was genuinely shocked that I could comb straight through my hair after using it after being in the water. It made such a difference to my ocean hair — I love it.

Simply the BEST.. better than all the rest

From the bottom of my salty heart, I genuinely adore this serum! I love the whole range but this one is my fave I think! My hair is always a birds nest when I’m finished diving and it’s usually a full scale battle to detangle it and get it hydrated again. After using this though, the knots come out with far less of a battle and my hair doesn’t feel dry and broken when it dries. 11/10 recommend!!

Poppy
11/10 BEAUTIFUL!

Honestly the most beautiful product! It’s so hard to find a product that actually rehydrates your skin after a day of sun and salt without leaving your face feeling heavy and sticky but the water cream is that unicorn. It’s light and unscented (which I absolutely love) but also restores everything the ocean took for the day! 11/10! Highly recommend for all the ocean girlies!

Immediate Relief After the Ocean

This is really lovely to use after a salty dive. It's perfectly light yet restoring, helping my skin feel hydrated, protected, and restored immediately after being in the ocean.

This Water Cream is exactly what I was looking for

This Water Cream is exactly what I was looking for, it is deeply hydrating without being sticky or oily. I felt the difference from the first use, and now I use it every day — even when I’m not going to the ocean.

Shaina Munro
Obsessed with this Hair Serum

I love how easy it was for me to brush my hair out after a surf! Usually my hair is a rats nest but it combed through like silk!

Hi Shaina, thank you so much for the love! We’ve all been there with the 'rat’s nest' hair after a good surf—it’s the ultimate post-ocean struggle. I’m so happy to hear the Sea Silk Hair Serum lived up to its name and helped you comb through like silk!

Mia, Professional Swimmer
A Serum Trusted by Professional Swimmers

I’m a professional swimmer and I’ve never found a serum like the Mermaid’s Secret Hair Serum. It’s incredibly hydrating and makes your hair feel so healthy and luxurious after time in the water. It’s perfect for anyone who spends a lot of time in or around the ocean. I absolutely love it — 10 out of 10. And it smells amazing.

Thank you so much, Mia! It truly means a lot coming from someone who spends so much time in the water. We created Mermaid’s Secret for ocean lovers like you who refuse to compromise healthy hair for life in the sea. So happy the Sea Silk Hair Serum is helping keep your hair hydrated and soft after your swim days

Lightweight. Calming. Ocean-Proof.

I love the water cream. It’s gentle and calming and soothes my skin at the end of a hot beach day. There’s no added fragrance in this one. A little goes a long way, and it sinks in quickly, with no shine or greasiness. Plus it layers easily under sunscreen the next morning.

Grace Yun
Super hydrating

The water cream feels lightweight yet deeply hydrating, without being oily at all. My skin still feels moisturised the next morning. It definitely feels like a premium line, and I highly recommend all three.
It would be even better if they came with a small pouch to carry all three together.😊

Thank you so much for this thoughtful review
We’re so glad the Water Cream feels lightweight yet deeply hydrating for you — that balance is exactly what we worked hard to achieve.

And we love your idea about a small pouch for the full ritual ✨ Noted!

I’ve been using this for two weeks straight now

I’ve been using this for two weeks straight now and really impressed. It makes my skin glowy and hydrated without being sticky or oily. I don’t just use it after the ocean I use it every single morning and night and I have noticed a difference in my skin.

Thank you for your review Stephanie!
We’re so happy to hear you’ve been using it consistently and seeing a real difference!! — that glow without the sticky or oily feel is exactly what Sea Shield Water Cream was designed to deliver.

We love that it’s become part of your morning and night routine, not just after the ocean ✨ That everyday barrier support is what truly makes the difference.

So grateful you shared your experience

I have been seriously pleasantly surprised with how much I love this hair serum

I have been seriously pleasantly surprised with how much I love this hair serum. I spend a huge amount of time in the ocean and have really long blonde hair. I have used tonnes of different products on my hair and this serum makes it feel so incredibly silky. This video isn’t after it’s air dried with the serum in which is just incredible . Will be re purchasing!

Thank you so much, Stephanie
Hearing this from someone who spends so much time in the ocean means the world — that silky, lightweight finish is exactly what Sea Silk was designed for.
So grateful you shared your video and experience with us

Really Lovely for My Daughter’s Hair

My daughter’s hair can get pretty knotty, and this has honestly made a big difference. It smooths everything out and makes brushing much less of a battle. It feels light in the hair and doesn’t leave that greasy finish some serums do. Smells nice too. Glad we gave it a go.

Thank you so much for your review Penny
We’re so happy to hear it’s made brushing easier and feels light without that greasy finish — that smooth, effortless result is exactly what Sea Silk was created for.
So glad it’s working beautifully for your daughter’s hair

Relief After the Water

Wow what a skin quencher! My face was all tight and warm and the cream felt really hydrating. I love that there’s no fragrance and nothing that irritates the skin when it’s already gone through a lot because of sun and salt exposure. I usually put on organic aloe vera gel from the fridge when I get home. But this was so nice to have in my bag.

Thank you so much, Emilie
We’re so glad it helped calm that tight, sun-warmed feeling — that kind of relief after salt and sun is exactly what Sea Shield was created for.
We love that it’s something you can keep in your bag and reach for straight away

This hair serum is incredible!

This is honestly the best hair serum I have ever used, and I truly mean that. I have really long hair and it’s a mission keeping it kept and this has made such a big difference, I’m now using it daily. Same with the cleanser, that is now my daily too, it leaves my skin feeling so good and clean I couldn’t be happier!
