Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Decyl Glucoside

What it does: Cleansing, Emulsion Stabilising

Community Rating: Mixed

Decyl Glucoside is a glucose-based surfactant. Surfactants help clean the skin by trapping oil, sebum, and dirt to be washed away.

It is created by reacting glucose with the fatty acids from plants.

This ingredient is biodegradable and non-toxic. This ingredient is commonly found in baby shampoos.

Decyl Glucoside is sometimes used to stabilize the UV filter Tinosorb.

Olaplex No.4 Bond Maintenance Shampoo contains this as ingredient number 9.

BondiBoost Thickening Therapy Shampoo contains this as ingredient number 4.

Parfum

What it does: Masking, Perfuming

Community Rating: Very Disliked

Parfum is a catch-all term for an ingredient or more that is used to give aroma to products. Parfum, or fragrance, can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "Parfum" in the ingredients list is a different mixture.

In the US, the alternative name for parfum is 'fragrance'. The term 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.

For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance. One example is Calendula flower extract. Essential oil ingredients still impart a scent or 'fragrance'.

Depending on the blend, it can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.

Products use parfum often to give products a scent or cover up smells of different ingredients.

The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.

Citric Acid

What it does: Buffering, Masking

Community Rating: Disliked

Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).

If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.

As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and look more even.

Large amounts of vitamin E found in argan oil helps the skin retain water. Argan oil also contains fatty acids such as linoleic acid, oleic acid, and palmitic acid. It is also a good source of lipids.

Another benefit of argan oil is skin-soothing. It can help reduce inflammation-related skin symptoms.

Traditionally, argan oil was used for its antibacterial and antifungal properties. However, argan oil contains fatty acids that may make it not fungal-acne safe.

Argan Trees are native to Morocco.

Biotin

What it does: Antiseborrhoeic, Skin Conditioning

Community Rating: Liked

Biotin is a B vitamin that is naturally produced by our bodies. It is also called Vitamin H.

Our bodies use biotin in the metabolism process. It also helps our bodies use enzymes and move nutrients around. A biotin deficiency can lead to brittle hair and nails.

More research is needed on applying biotin topically. However, taking biotin orally has been shown to help nourish the skin, hair, and nails. They play a role in forming skin-hydrating fatty acids.

Biotin is water-soluble. It can be found in foods such as fish, eggs, dairy, nuts, and meat. Vitamin H stands for "haar" and "haut". These are the German words for hair and skin.

We recommend speaking with a professional if you have any questions or concerns about this ingredient.

You honestly shouldn’t be using this unless you have color treated hair, which is something I realized after using this for awhile. This is very heavy, I found that it weighed my hair down and made it look lifeless.
