As someone with fine hair and an oily scalp, finding the right shampoo and conditioner can be difficult. I want products that will volumise my hair while being lightweight and non-drying. I also seek a shampoo and conditioner that will give my hair a lift for days, not just on wash day.
The Redken Volume Injection Shampoo and Conditioner are highly regarded by people with fine, flat hair. This volumising duo claims to deliver visible body and thickness while leaving strands hydrated and shiny.
In this review, I share why the Redken Volume Injection Shampoo and Conditioner are easily some of the best products I’ve used for my fine hair and oily scalp, plus an exclusive discount code for 20% off!

1. Redken Volume Injection Shampoo
£21.75 for 300ml

The Redken Volume Injection Shampoo is designed to cleanse and volumise fine, flat hair to give it visible body, fullness, and improved texture. It claims to leave hair silky soft and shiny.
This shampoo has a sweet and fresh scent. I can’t pinpoint an exact fragrance note, but it smells nice.
In terms of texture, the shampoo is quite thick and creamy. A bit of product goes a long way, and it works into a creamy, non-stripping lather. I use a 50p coin-sized amount, and this provides ample coverage for my entire scalp. The product rinses away easily and doesn’t leave a greasy residue.
This shampoo gives my hair noticeable volume, more body, and doesn’t make my hair feel as slippery. Instead, my hair has more grip and fullness, which prevents it from going greasy as quickly. It also makes my hair easier to style. The shampoo is fairly hydrating and gentle.
Before using this shampoo, I had to wash my hair every 2 days, as it became oily quickly. Now, I can get away with leaving my hair for 3-4 days before needing to wash it again. Sure, I may need a touch of dry shampoo in between washes to keep my hair looking fresh, but this shampoo means my hair doesn’t get oily anywhere near as quickly.
Rating: 5 stars
This is easily one of the best volumising shampoos I’ve tried.
2. Redken Volume Injection Conditioner
£23.85 for 300ml

The Redken Volume Injection Conditioner is designed to volumise fine, flat hair. It claims to be weightless while effortlessly detangling hair, leaving it manageable, silky soft, and with a mirror-like shine.
The conditioner has the same sweet, fresh scent as the shampoo. Although once the shampoo and conditioner are rinsed out of your hair, the fragrance disappears.
This is a thick and creamy conditioner. A little bit of product goes a long way. Again, a 50p coin-sized amount is enough to coat the ends of my hair. The conditioner washes out easily with no greasy residue.
I rarely condition my scalp as it tends to get way too greasy. But actually, I can get away with using this conditioner on my scalp, as it’s incredibly lightweight and doesn’t weigh my hair down. So if my scalp ever needs a bit of TLC, I’ll happily apply this conditioner.
This conditioner gives my hair volume, leaves it soft and shiny, and hydrates it. While it’s not the most nourishing conditioner I’ve tried, my oily scalp and sleek hair texture mean I don’t want an ultra-hydrating formula. It’s just too heavy for my fine hair otherwise. But this conditioner gives my strands ample moisture while retaining their silky nature. I agree that this conditioner leaves my hair in a manageable condition with no tangles.

This volumising conditioner is perfect for my hair.
The Redken Volume Injection Shampoo and Conditioner are must-haves for fine, oily hair

The Redken Volume Injection Shampoo and Conditioner meet their claims and give my hair lots of body and noticeable volume. They’re weightless formulas, extend how long I can leave my hair before it needs washing again, and give my hair lasting fullness. Since using this duo, my hair isn’t as greasy and is in great condition.
Instead of £45.60, you can get the shampoo and conditioner for just £36.02 at LookFantastic with my exclusive discount code LFTFBLOGSARAH. While this is on the more expensive side for a shampoo and conditioner, the quality of these hair products and the results make the price tag so worth it.
I’ll definitely repurchase this shampoo and conditioner!
I’ve never heard a bad word about Redken, so this review definitely solidified that for me! I think this duo would be great for me too as I have to wash my hair more often than I’d like to. Thanks for the discount!
