The Ordinary Sulphate 4% Cleanser for Hair & Body
Gentle Cleansing Formula for Daily Use
Sulphate 4% Cleanser for Body and Hair offers a gentle-is-essential approach to effectively cleanse body and hair. The low foaming product contains SLES-2, a milder sulphate that has been incorporated into the formula to be gentle on the skin, and cleanse hair without additional colour fade. The molecular structure of SLES-2 is designed to provide effective cleansing at a lower concentration to minimize concerns with potential irritation associated with the use of sulphates.
Currently scores 4.3/5 on the Deciem website. I absolutely love the Shampoo & Conditioner and have repeatedly purchased it. My hair has never felt or looked so clean, light, shiny yet manageable.

The Ordinary Behentrimonium Chloride 2% Conditioner
Lightweight Conditioning Formula. Behentrimonium Chloride 2% Conditioner is a minimalistic formula that avoids the bulky ingredients typically found in conditioners. This means more manageable hair with less weigh down.
Currently scores 4.5/5 on the Deciem website. I absolutely love this conditioner and have repeatedly purchased it. It literally detangles hair in seconds and leaves it feeling so light and shiny.
The Ordinary Natural Moisturizing Factors + HA for Scalp
A Lightweight Hydrating Serum for Scalp. Natural Moisturizing Factors + HA for Scalp is a milky serum that contains a combination of ingredients that mimic the function of natural moisturizing factors (NMF), as well as hyaluronic acid (HA) and squalane that are naturally produced within the skin. With regular use, this formula supports hydration through scalp skin barrier protection.
Currently scores 4.2/5 on the Deciem website.
The Ordinary Multi-Peptide Lash & Brown Serum
A multi-peptide lash and brow serum for thicker, fuller and healthier lashes and brows.
The Ordinary Multi-Peptide Serum
Deciem says that this concentrated formula is designed to support hair health to look thicker, denser, fuller and healthier.
How to use: Apply a couple of drops to a clean and dry scalp and massage in thoroughly. It´s best to use it daily at bedtime. I expected the texture of this to be thicker but it´s a very watery serum. I haven´t used it enough to see a difference, so please check reviews on the Deciem website and Deciem Chat Room Instagram here.

The Ordinary Hemi-Squalane Oil
Hemi-Squalane has greater spreadability and leaves a light and dry after-feel, making it very suitable for reducing hair frizz.

The Ordinary Squalane Oil
The Ordinary 100% Plant-Derived Squalane Oil has to be my favourite oil. It’s amazing for hydration, great for dry under eyes mixed in with a little concealer and amazing for lips too. Apart from skin, it can also be used in the hair to increase heat protection, reduce breakage, and add shine.
How to use in hair: Work through cleaned damp hair. You may find different ways to work better for you. It can be a case of trial and error.

Chia Seed Oil
Deciem says that this oil is an immediately-soothing, calming and nourishing skin oil that contains an exceptionally high concentration of alpha-linolenic acid, an important essential fatty acid, and linoleic, oleic, stearic as well as palmitic acids, together with multiple vitamins, minerals and antioxidants. This oil also adds softness, sheen and strength to hair.

Moroccan Argan Oil
Deciem says this 100% pure Moroccan Argan Seed Oil extracted through a cold-pressing that preserves the integrity of the oil’s fatty acids, vitamins, phenols (including caffeic acid) and carotenes. Argan oil’s main fatty acid content is made up of oleic acid and linoleic acid. The oil supports healthy skin and reduces the appearance of flaking. It also adds soft sheen and strength to hair.
