What do hair moisturisers and serums do?
What is hair moisturiser used for?
It’s all in the name - a hair moisturiser gives your hair strands an intense dose of moisture to make them stronger, smoother, and shinier. Most of the time, they have a creamy consistency.
Depending on the type of moisturiser you use (you can find hair masks, hair creams, and leave-in hair moisturisers), a hair moisturiser can be left in for anywhere from 10 minutes to overnight for all the nourishing properties to soak in and take effect.
They’re often used after you’ve rinsed out your shampoo and conditioner, however some can be used on dry hair, while others don’t require any rinsing out.
What does hair serum do?
A hair serum is a product (most are a gel or oil-like consistency) that coats the surface of your hair to help repair, strengthen, and thicken each strand.
Generally speaking, this has the effect of reducing frizz, adding moisture, preventing and repairing damage, and smoothing flyaways to make hair stronger and shinier. Different serums have different purposes however, so you should choose one depending on your own hair goals and concerns.
So, what are the advantages and disadvantages of hair serums and moisturisers?
Pros
Cons
Choosing a product based on your hair concern
The right hair moisturiser or serum for you will largely depend on your hair type, texture, density, as well as your own personal preferences and specific hair concerns.
Think about what you want your hair care product to achieve - we’ve listed some hair goals below.
Prevent and repair damage
Doing things like bleaching, colouring, and heat styling our hair can cause it to fray, split, and break.
While a cream or serum can’t glue your split ends back together (the only real way to get rid of them is to cut them off), you can partially mend these damaged hair strands and strengthen them to prevent further splitting and breakage.
Cream-based and oil-based formulas tend to be more effective at preventing and repairing damage. You can also use a hair oil, as these penetrate the hair cuticle and treat the hair follicle, while a serum sits on the hair’s surface.
Some moisturisers and serums that help repair damage include the georgiemane 10 Minute Hair Mask, the Kérastase Masque Extentioniste, and the Olaplex No. 3 Hair Perfector.
Keratin is often found in moisturisers and serums for damaged hair, as it’s great for preventing hairs from splitting and breaking.
Protect against heat and pollution
If you live in a humid climate, use heat styling tools regularly, or are concerned about air pollutants damaging your hair, then it’s recommended that you opt for a quick-absorbing, lightweight formula that won’t leave your hair feeling greasy.
Ingredients like lavender oil and jojoba oil can help detangle hair and protect it against heat.
Reduce frizz and maintain your natural hair
Whether you’ve got bouncy ringlets or dead-straight hair, frizz is not your friend. The right anti-frizz hair smoothing serum can detangle knots and reduce overall hair dullness to add shine to your locks and make them easier to manage.
Even if you’re after a sleeker do, don’t opt for a cream or a product with a thick consistency if you have finer hair, as these could weigh your hair down and make it look oily. Some products that can help make your hair silkier include John Frieda Frizz Ease and Biosilk Silk Therapy.
Lightweight products with moisturising ingredients - such as argan oil, jojoba oil, and macadamia oil - can help smooth your hair and make it easier to run your hands through.
Add hydration
If your hair is parched, cream-based (if you have coarse, denser hair) and oil-based formulas tend to be more effective in replenishing your hair’s moisture - particularly if you have coloured or chemically-treated hair.
You can also opt for overnight treatments, letting you wake up with shiny, nourished hair.
Moisturisers and serums that add intense hydration often contain ingredients like coconut, jojoba, argan, and macadamia.
Promote hair growth
Whether you’re experiencing hair loss or thinning, or you just want your hair to grow longer, quicker, a hair growth oil or serum - such as the Bondi Boost Intensive Growth Spray - may help. You can also find dedicated hair loss treatments that sometimes deliver better results.
If you’re experiencing hair loss, it’s a good idea to see a medical professional to find out the root cause for this, as well as eating a healthy, balanced diet.
Look for products with castor oil - it’s an ingredient renowned for helping hair grow.
Common ingredients in hair moisturisers and serums
Ingredients to look for
This isn’t an exhaustive list, but the following ingredients in a hair moisturiser or serum are known to repair and nourish hair.
- Argan oil can moisturise your hair, promote hair growth, and protect it from damage. It can also reduce the incidence of breakage and split ends, keeping your hair healthy as it grows.
- Coconut oil helps maintain your hair’s natural proteins, which can often be lost when hair is heated or brushed.
- Avocado oil softens hair, making it useful for treating damaged hair.
- Jojoba oil keeps the hair and scalp moisturised.
- Shea butter is packed with vitamin A, vitamin E, and essential fatty acids, all of which help lock in moisture and tame frizzy hair.
- Macadamia seed oil is moisture-rich and is packed with antioxidants that protect and strengthen hair.
- Castor oil, including Jamaican black castor oil, nourishes the scalp which can help grow hair faster.
- Keratin can help maintain the structural integrity of your hair and protect it from the damage caused by sun exposure, dye, and chlorine.
- Biotin is important for hair health, as it helps prevent hair loss and brittle hair, making it a great ingredient in hair and scalp serum.
- Glycerin is a humectant that helps your skin and hair retain moisture, making it a great ingredient to look out for if you're suffering from hair dryness.
Ingredients to be wary of
These ingredients can be damaging to your hair, so it’s a good idea to do some digging into what’s in a moisturiser or serum before you buy it.
- Parabens extend the lifespan of your hair product by preventing the growth of bacteria, but are known to cause skin irritation and are a suspected carcinogen.
- Silicone makes hair shinier, but this is a skin-deep benefit, as it also dries it out and prevents moisture from penetrating it, leading to frizz and breakage.
- Sodium lauryl sulfate (SLS) and Sodium laureth sulfate (SLES) can cause skin and eye irritation, so you’re better off avoiding them if you experience skin sensitivity.
- Phthalates make a hair product softer to the touch and easier to apply, but they’re also thought to interfere with hormonal activity.
- Triclosan is in many hair products to prevent the growth of bad bacteria, but it can also irritate your skin.
- Polyethylene glycols (PEGs) are a thickening agent found in hair care products that often strip the moisture from your hair.
While it’s difficult to avoid all of these ingredients, it’s helpful to be aware of the potential damage they can do to your hair so you can do your own research on products that might be right for you.
At the end of the day, these aren’t the ingredients that will nourish your hair, so your hair care routine can do without them.
Other considerations
"Green" beauty
With consumers becoming more and more concerned with ethical beauty products, there are plenty of hair care products on store shelves that are kinder to the planet.
You can find cruelty-free products that haven’t been tested on animals, vegan products, and products that don’t have ingredients whose harvest is known to be harmful to the environment (such as palm oil).
You can also look for products with minimal, plastic-free packaging to help reduce landfill waste.
Skin sensitivity
If you have sensitive skin, you should consider avoiding synthetic fragrances and colours. They serve no other purpose than to make your hair moisture cream or serum smell and look nice, and they’re known to cause skin irritation.
Price
The price of a hair moisturiser or serum can vary greatly, with a tub or bottle costing anywhere from $5 to $300 and upwards. A higher price often indicates higher quality ingredients, however there will be a big mark up if you’re buying from a luxury brand.
If you’re interested in a pricier hair treatment but don’t want to fork out money for something that may not even work for your hair, check whether you can get or buy a smaller amount to try it out.
Hair masks, for example, often come as individual sachets for 1 or 2 uses, and can cost anywhere from $2.50 to $15. You can also often get free testers for products from the beauty counters at many department stores - you’ve just got to ask.
Application tips
These are some general tips for how to make the most of your hair moisturiser or serum, but you should consult the product label for its recommended use.
- Start by applying the hair moisturiser or serum to the ends of your hair and working your way up to the middle - this will help ensure you apply product where you need it most (that is, your drier ends).
- Add 1-2 pumps of serum to damp hair before you blow dry it, and a few drops after it’s dry. You can also apply a small amount on days that you don’t wash your hair.
- Avoid applying serum to your roots or scalp, as this can cause a build-up of product and make your roots look oily.
The bottom line
It’s easy to be swayed into buying "holy grail" products, but the truth is, a product can be life-changing for one person and totally ineffective for the next.
Reading reviews, doing your research into a product’s active ingredients, and considering your own hair concerns should help you find a serum or moisturiser that makes your locks look and feel great.
