A - Getting started

A1 - Does my hair need protein or moisture? 

An optimum protein-moisture balance is the key to incredible hair.


A simple test you can do to determine if your hair needs more moisture or protein is by stretching a strand of your hair down towards the ground and seeing how far it extends before breaking.


Balanced hair = strand stretches a little then returns to original length without breaking


Protein overload = strand keeps stretching without breaking (hair feels frizzy, limp and mushy)


Moisture deficient = strand stretches very little before breaking (feels dry, brittle and like straw)


Note that your moisture/protein balance will change all the time, so it’s worth doing this test every month.

A2 - What products to use if I need more protein/moisture?

Balanced hair: use entire Merwave range (numbers 1-5)


Protein deficient: use numbers 1-5. Experiment using more Feed Treatment (number 3) for protein hit


Moisture deficient: skip number 3 (Feed Treatment) as you don't need more protein right now. Use more Repair Conditioner and apply Deep Conditioning Mask once or twice per week to hydrate your hair. 


Worth noting wavy hair is normally moisture deficient. So don't be alarmed if your hair currently feels dry and brittle. 

A3 - I’ve used other products and heat tools before, will this cause issues?

If you’ve used heating tools and harmful products (hair dyes, silicones etc) before then your hair may be damaged. So more protein will be required to repair your hair.  


If you want a hard reset, wash your hair using a clarifying shampoo. This will remove any old product build up so you can start from scratch. It will leave your hair dehydrated and super dry though, so make sure you deeply condition after. 


Bear in mind, if your hair is really damaged, then it will take some time for it to get back to full health.

A4 - Can I brush my hair?

Only when it’s soaking wet and coated in conditioner. Use a tangle teaser or wide tooth comb to detangle. 


Brushing your hair when it’s dry causes tension on your hair strands which leads to breakages. 

B - Wash day questions

B1 - What's the process?

Full video demos can be found here. We advise watching them to see the routine in action. 


This is where the fun begins! The process may look daunting, yet it’s super easy once you’ve done it a couple of times. 

B2 - What quantities should I use? 

Everyone’s hair is different. Some people (like me) have lots of hair so need more product. Others have finer hair that reacts better to less product. There is no right or wrong amount.


Experiment with different quantities until you discover what works best for you. Start off with less and add in more if required.

B3 - How do I dry my hair?

Few options depending on how much time you have. The big no no is blow drying. This will cause all sorts of problems with your waves.


Option 1: Diffuse


Full video on this page. Quickest method if you’re in a rush. Use on a low heat and low speed. Post diffusing your hair may look a little crunchy, so you’ll need to break the cast (see how here).


Option 2: Air drying


Healthiest option, yet also the longest. Just let your hair dry as normal.


Option 3: Microfibre hair towel and air dry/diffuse combo


Best of both worlds. The microfibre hair wrap will absorb excess moisture. You can then air dry or diffuse to finish it off.

C - Post wash questions

C1 - When should I start seeing results? 

Some people’s waves will be unleashed after the first wash. Others will take time. It all depends on how you’ve cared for your hair prior to starting this process.


If you’ve been using products that contain sulphates, silicones, parabens and damaging it using heating tools (blow drying, straighteners, curlers etc), then your hair will likely be damaged. It’ll therefore need to go through what’s called the ‘’transition stage’’. Read this article about it.


Your hair is a living thing (like your skin). So the longer you use the products the healthier your hair will become, which equals more defined waves.

C2 - What do I do on non-wash days? How to refresh

Product build-up, humidity, sleeping, day to day life. There are multiple reasons why your waves lose definition on non-wash days. They become weighed down, lose their shape, appear messy.


Which is why you need to understand how to quickly refresh your waves.


This guide (with video demo) shows you how to do that. Click here to watch.

C3 - How to protect my waves when sleeping?

Nothing worse than having a great wash day, going to sleep and waking up looking like you’ve been dragged through a bush (frizz, tangles etc).


You must protect your waves at night. Firstly, swap your cotton pillow case for a silk pillow case. Silk results in less friction with your hair, which is a big cause of frizz. A silk hair bonnet for sleeping in will also keep your hair tidied away and secure. Putting your hair up in a pineapple will also keep it safe.

C4 - How often should I wash my hair?

Depends on your hair type and lifestyle. We’ve compiled a full guide on how often you should wash your hair. Read it here. 

D - Help! My hair is...

D1 - My hair is crispy/crunchy

Likely because you haven't broken the cast. The Cast Foam creates a crispy cast around your waves as they dry. You need to break the cast when your hair is fully dry by clapping or scrunching it out. This is called ‘scrunching out the crunch’. There’s a video on this page showing you how to do this. If it still feels a little dry try adding a few drops of oil through your hair. 

D2 - My hair feels producty

Few reasons why... 


1. Used too much styling product (steps 4 & 5). Next time use less. 

2. Haven't scrunched out the scrunch as mentioned in question D1. 

3. Not use to having product in your hair 

D3 - My hair is dry, brittle and feels like straw

This is due to a lack of moisture. So, remove Step 3 (Feed Treatment) from your next wash.


At this stage your hair doesn’t need protein. It’s craving moisture. So treat it to a deep condition using our Deep Conditioning Mask. Wash hair as normal, apply mask and leave on for 30 minutes, rinse off, then style as normal.

D4 - My hair looked great yesterday, but now a mess

Main reason why is because you didn’t protect it when sleeping (see question C3).


You may just be going through the transition stage (question C1) so your hair is reacting differently to the new products. If this is the case you need to persevere. It will get better, as members in our group have confirmed.


If your hair is messy in the morning, perform a refresh. See question C2.

D5 - Lots of hair is coming out when I brush

It’s normal to lose between 50-100 strands of hair per day. You may notice you’re losing more hair, yet the main reason for this is because you’ve gone from brushing your hair daily to only brushing it in the shower when conditioning it.


Instead of brushing out 50+ strands daily, you’re now only brushing it twice a week, which has caused a backlog of dead hair strands.


If you do see chunks of hair coming out then it’s advised to speak to your doctor.
