In my IG story a few weeks ago, I showed a couple of hair care products that seemed to have different formulas. A biochemist reached out to me to help explain the confusion with the ingredients and labeling as some can be nonspecific. I will discuss that at the end of this blog.
If you pay attention to product marketing, you will notice a major change in the way products are sold to consumers. as people become more informed, due to accessibility of knowledge online, the trend has moved towards including science and research claims to appeal to those who actively take an interest in their care rather than celebrity endorsements.
The shift has been towards more plant-based, chemical free and natural products although some of these terms leave more to be desired and plant extract is readily becoming one of the buzzwords.
When a new product is being sold, it is often highlighted that it contains many beneficial plant extracts that will do X,Y and Z for your hair and skin.
More people are trying to go deeper than the slogans and fancy graphics to find out what these ingredients do and if they are actually safe.
A plant extract is the substance which has been removed from the main plant tissue with the hopes of providing a more active ingredient for use in food stuffs, pharmaceutical or cosmetic products.
Extracts can be derived from different areas of the plant including but not limited to the root, stem, bark, leaves and seeds. This means that a single plant can yield several different extracts.
The process of extraction varies depending on the plant and use. Most extracts are obtained by using a solvent such as water, ethanol or hexane.
It can be conducted at home using a pestle and mortar or under strict lab conditions. The quality and efficacy of the extraction is dependent of the initial plant, processing and storage.
Achillea Millefolium (Yarrow) Extract – is added to a product to reduce the appearance of dry or damaged hair by reducing flaking and restoring suppleness. It is effective for treating dandruff, itchiness, scalp irritation and oily scalp. It has also been shown to help counteract hair loss. Regular use of a strong yarrow tea will lighten hair.

When making extractions, the plants is broken down and will release and make different cells more available. Some extracts will definitely contain protein or amino acids such as soy. While the processes used may render the proteins inactive due to denaturing, it is hard to know for certain. If a hydrolyzed plant is listed, then for sure protein is present. Hydrolysis is a series of enzymatic reactions used specifically to liberate proteins and make them more bio active. If you are avoiding protein do not be put of by plant extracts as the amount of protein, if any may be negligible. It is best to check with the manufacturer as only they will know the method of extraction used as that greatly affects the yield.
Here are the two products I mentioned at the beginning:
Giovanni Direct Leave in Conditioner: These are almost identical formulas with different descriptors from what the biochemist explained to me. The FDA requires scientific names. Also, there are different requirements for online mail order items. It’s the same plant extracts in both (for example, yarrow is the common name for Achilles millefolium). Pretty much any “extract” is going to contain protein unless it specifies that it’s an oil extract.
But as I mentioned above, it’s best to check with the manufacturer as only they will know the method of extraction used as that greatly affects the yield.
The biochemist also explained to me that, “As far as the proteins in general, there’s a lot of misinformation in the curly community. Proteins are actually super complicated and each protein has its own set of physio chemical properties that influence its behaviors.
Some are extremely resistant to denaturing. Even with high, acidity, high heat, etc Most are in the form of “hydrolyzed” proteins- broken down into amino acids.
Our hair is essentially dead and smaller protein components can fill in breaks in the hair shaft. That’s why it doesn’t last indefinitely.
They bond with the hair but aren’t a part of it, so eventually you need more when it washes away. So people with high porosity or damaged hair may respond more to low levels of protein in daily products like the Giovanni leave in”.
