Why You’ll Love Our Hair Oils & Shine Serums
Our collection is designed to help you:
-
Boost Shine Instantly – Add mirror-like gloss from mid-lengths to ends.
-
Control Frizz & Flyaways – Smooth the cuticle for a sleek, polished finish.
-
Nourish Dry Ends – Replenish moisture and softness where hair needs it most.
-
Protect From Styling Stress – Many formulas help protect against heat, humidity, and breakage.
-
Enhance Color & Dimension – Shine serums and oils make highlights and tones appear richer and more vibrant.
Most products can be used on damp or dry hair, making them easy to layer into your existing wash-and-style routine.
Find the Right Oil or Serum for Your Hair Type
-
For Fine or Thin Hair
Look for lightweight serums and dry oils that add shine without weight. A few drops are usually enough for a soft, glossy finish that won’t flatten your style. -
For Thick, Coarse, or Curly Hair
Richer argan, coconut, or multi-oil blends help deeply nourish, reduce volume where needed, and tame frizz for smooth, defined, touchable hair. -
For Damaged or Color-Treated Hair
Choose repair-focused oils and serums with added proteins, vitamins, or bond-supporting technology to help reduce the look of split ends and improve softness over time. -
For Everyday Finishing & Styling
Go for multi-use treatments similar to Moroccanoil-style oils—perfect for blow-drying, air-drying, or finishing dry hair with extra shine and smoothness.
How to Use Hair Oils & Shine Serums
-
Apply 1–3 pumps or drops (depending on hair length and thickness) to damp hair, focusing on mid-lengths and ends.
-
For added shine, smooth a small amount onto dry hair after styling.
-
Avoid the root area if you’re prone to oiliness—your ends need it more.
-
Can be layered with leave-in conditioners, curl creams, or heat protectants as part of your regular routine.
Perfect For
-
Dry, dull, or frizzy hair
-
Color-treated and chemically processed hair
-
Curly, wavy, or textured hair needing definition and moisture
-
Fine hair that needs light, non-greasy shine
-
Anyone who wants salon-finish gloss at home

Let customers speak for us
from 3255 reviewsCosmetic World never disappoints! They always have what I’m looking for and evidently really care about providing excellent quality products and customer service.
I was a little worried about ordering from Canada given the tariff situation and the sometimes dodgy sites selling Shades of EQ. However, everything was on-time and legit – I could not be happier!
Prompt, helpful service paired with prices well below salon RRP makes shopping here a pleasure. Orders arrive quickly and exactly as described, so you feel taken care of from checkout to unboxing. If you want reliable service and real savings on pro‑grade beauty products, this store delivers both.
Customer service that goes above and beyond. I needed to add to my order before it shipped. I was called and it was modified for me no problem. Very happy with the products as well.
The employees seem lovely and the products are authentic. They are professional and precise. I can't say enough good things! I will continue to purchase from this store.
Cosmetic World has a great variety of hair colour products. The customer service was top-notch: excellent communication and fast shipping. And the shipping was free for the products I ordered. In addition, the prices were reasonable.
Am so grateful to have found this distributor of European hair colour. Will definitely make future purchases.
Thank you Cosmetic World!
I've been using this hair color for 2 years now and no complaints! It gives great coverage for my greys and easy to mix and apply.
J'ai aimé le produit. Satisfaite du résultat de couleur
Cosmetic World was so helpful and professional. I ordered some hair dye and came within 2 days without a hitch. Thank you Cosmetic World!
Using the reasonably priced INOA hair dye I wondered if any developer would do...but this product line developer has some benefits for hair built in to this! Add to that so far I have dyed my hair Twice and still have lots left makes this a great value. I had been buying hair dye for the online mail subscription service paying a fortune and then shipping on top of that despite doubling orders which should have worked. That product faded so quickly unlike INOA which lasts even with red hair. Plus I like that as long as I do not mix this developer with the dye I can add a little more red in the summer or go a little more darker in the winter just by adding a complimentary color to go with the base and developer..saving the rest of the product for the next time needed..The bottle goes a long, long way and gives me the power to find the subtle shade differences that make me so happy I am a red head.
My order was delivered quickly and everything was as I expected.
This hair colour passed my 7 days of patch test (behind the ear), 30 minutes duration each time, without any adverse reactions. I think I have found a keeper for my ultra sensitive skin. The colour is amazing and covered all my greys. I used 10V Oxy colour with it.
My hairdresser recommended Cosmetic World to me. Their selection is superb with high quality products. I was able to find all the products I was looking for in one quick browse. The delivery fee was affordable and the products were delivered quick in a well packaged box. I highly recommend Cosmetic World to anyone looking to buy high quality and yet affordable hair products. If you can't make it in person, the delivery is a breeze!
I’ve been using Nioxin shampoo and conditioner for some time now and love it. But I want to praise Cosmetic World in particular. I discovered them just recently when I was comparing prices and they had the best prices by far, including all of the usual big discount retailers. This was my first time ordering from them and I was a little anxious about being in the US and ordering from Canada. But the shipping was not expensive and it arrived quickly and in perfect condition. I’m very pleased and will order again!
The perfect green to fade my daughter’s hair from blue teal to like green! We love anything joico!!!!!
