Lets start with the history of Henna.
Lawsonia inermis (Lythraceae) : These are the the name Henna goes by in the plant world. The Evergreen shrub and or tree is heavily scented growing over 20ft (6M). This is a beautiful plant with narrow pointed leave with beautiful clusters of pink or white flowers and blue/black berries.
Lawsonia Inermis (Henna) is Native to North Africa, Middles East and the Indian subcontinent. Henna grows in sunny areas and is used as a hair restorative and hair color.
The best time for cultivation is at the peak of the growling season. The leaves and bark are used in many ways. This plant is a power house, let's get into some of it's amazing qulaties.
Coumarins: These are organic compounds found in henna and other plants. Coumarins can have various effects and are often associated with a sweet scent.
Naphthoquinones: Lawsone is the most well-known naphthoquinone found in henna. It is responsible for the dyeing properties of henna.
Flavonoids: Flavonoids are a group of polyphenolic compounds found in many plants. They can have antioxidant and other beneficial properties.
Sterols: Sterols are a type of organic molecule found in plant cell membranes. They can have various functions in plants.
Tannins: Tannins are polyphenolic compounds that are often responsible for the astringent taste in plants. They can also have antioxidant properties.
These compounds contribute to the various properties of henna, including its ability to dye hair and skin, as well as potential medicinal uses. Henna has been used traditionally for its cooling and soothing effects on the skin, and some people believe it has benefits for conditions like burns or skin irritations. However, it's essential to note that while henna is generally considered safe for external use, individual reactions can vary, and it's crucial to use it with caution and do a patch test if you have sensitive skin.
Henna does indeed leave a lasting stain within the cortex of the hair shaft, which can be considered a type of pigment deposit within the hair. This is why the color change from henna is often referred to as "permanent," although it can gradually fade over time and may require touch-ups.
The lawsone molecules in henna penetrate the hair's cuticle and bind to the proteins within the cortex. As a result, the color remains within the hair shaft even as the outer layer (cuticle) is subjected to wear and tear.
This long-lasting color deposit is a unique characteristic of henna and sets it apart from temporary hair dyes, which only coat the hair's surface and can be washed out more easily.
So how does Henna actually work to color the hair?
Henna's coloring properties are primarily due to the attachment of lawsone molecules to the disulfide bonds within the hair shaft. Here's how this process works.
The hair shaft is primarily composed of three types of chemical bonds:
1. **Disulfide Bonds:** These are the strongest type of chemical bonds found in the hair shaft. Disulfide bonds form between sulfur atoms in the amino acids that make up the hair's protein structure, known as keratin. These bonds are responsible for the hair's strength and resilience. Disulfide bonds can be broken and reformed with chemical treatments, allowing for changes in hair shape, such as in perming or straightening.
2. **Hydrogen Bonds:** Hydrogen bonds are weaker than disulfide bonds but still play a significant role in the hair's structure. These bonds form between the hydrogen atoms of one amino acid and the oxygen atoms of another amino acid within the same or neighboring protein chains. Hydrogen bonds are responsible for the temporary changes in hair shape caused by heat styling, such as curling or straightening with a flat iron. They can be temporarily altered by applying heat and reformed when the hair cools.
3. **Salt Bonds (Ionic Bonds):** Salt bonds, also known as ionic bonds, are formed when positively and negatively charged atoms or groups in the amino acid side chains attract each other. These bonds are weaker than both disulfide and hydrogen bonds and play a minor role in the overall structure of the hair. They can be influenced by changes in pH levels and can affect the hair's texture and manageability.
Understanding these bonds is crucial in the field of hairstyling and hair care, as different treatments and products can impact these bonds, leading to changes in the hair's appearance and structure. Proper care and maintenance can help keep these bonds intact and promote healthy hair.
Disulfide Bonds in Hair: Hair's structure is held together by various types of bonds, including disulfide bonds. Disulfide bonds are strong chemical links between sulfur atoms in the hair's protein structure, known as keratin.Lawsone Molecules: Henna contains a natural dye molecule called lawsone. When henna paste is applied to the hair, lawsone molecules are released from the henna and become activated.
Chemical Reaction: Lawsone molecules have an affinity for sulfur atoms, which are found in abundance in the hair's disulfide bonds. The lawsone molecules chemically bond with the sulfur atoms in the disulfide bonds.
Color Development: As lawsone molecules attach to the disulfide bonds, they create a stable and long-lasting color within the hair shaft. The resulting color can vary from red to reddish-brown, depending on factors such as the individual's natural hair color and the specific henna used.
Long-Lasting Effect: This color is often referred to as "permanent" because it doesn't wash out immediately. However, it does gradually fade over time as the outer layers of the hair naturally shed.
Lawsone, a naphthoquinone compound, is the primary active ingredient in henna responsible for its dyeing properties. It's the presence of lawsone that gives henna its characteristic red or reddish-brown color when applied to hair or skin.
Staining Process: When henna leaves are crushed and processed to create a paste, lawsone is released. This lawsone-rich paste is then applied to hair or skin.
Binding to Keratin: Lawsone has an affinity for the protein keratin, which is abundant in hair and skin. It forms a chemical bond with the keratin molecules in these tissues.
Color Development: As lawsone binds to the keratin, it creates a stable and long-lasting color. The resulting color can range from a vibrant red to a deeper, reddish-brown hue, depending on factors like the initial hair color and the length of time the henna is left on.
Permanent Effect: The color imparted by lawsone is often referred to as "permanent" because it doesn't wash out immediately. However, it does gradually fade over time as the outer layers of the hair or skin naturally shed.
Lawsone's ability to bind to keratin and create a lasting color is a unique characteristic of henna and sets it apart from temporary hair dyes, which merely coat the hair's surface and can be washed out more easily. This natural dyeing process is one of the reasons henna has been used for centuries as a hair and skin coloring agent.
However there is something everyone is overlooking. It has the ability to break into the cortex of the hair shaft the same way professional hair color does. It's a protein based color agent that binds to the keratin within the cortex or the hair shaft. If you have low porosity henna will cause your hair to break over time.
Henna's ability to bind to protein can indeed have different effects on hair, depending on its porosity and sensitivity to protein. Here's a more detailed explanation:
High Porosity Hair: High porosity hair typically has a more open cuticle layer, which can lead to moisture loss and a porous, rough texture. Henna's protein-binding properties can be beneficial for high porosity hair, as it helps fill in gaps in the hair shaft, making it feel smoother and more structured. It can also add weight to the hair, making it appear fuller.
This is all a vanity metric. Henna gives the APPERANCE of smoother and fuller hair but it's a illusion. The molecules in Henna are binding to the protein within the hair shaft filling it up giving the illusion of thicker fuller hair.
Low Porosity Hair: Low porosity hair has a tightly closed cuticle layer. Henna's protein-binding effect can make the cuticle layer even tighter which causes hair weathering and breakage over time with regular use.
Henna is a natural protein treatment that leaves behind pigment that lives in the hair shaft forever unless manually extracted with a chemical that can safely detach the lawsone molecules from the disulfide bonds of the hair shaft.
For individuals with low porosity hair who are protein-sensitive, henna can indeed be problematic because it adds more protein to the hair, which can lead to an undesirable stiffness and dryness.
Understanding your hair's porosity and how it reacts to different treatments is crucial for effective hair care. If you have low porosity hair and experience dryness or negative effects from henna, it's advisable to explore alternative hair coloring or conditioning options that better suit your type and needs.
While henna is generally considered safe for external use, it's important to note that overuse or improper application of henna, especially if you have low porosity hair or a sensitivity to protein, could potentially lead to hair issues over time. Here are some concerns to be aware of:
Protein Overload: Henna is rich in protein, and excessive use on low porosity hair could lead to protein overload. Too much protein can make the hair brittle and prone to breakage, potentially leading to thinning or damage.
Dryness: As mentioned earlier, henna can have a drying effect on some hair types, particularly low porosity hair. Prolonged dryness can make the hair more susceptible to breakage and, in extreme cases, contribute to hair thinning.
Buildup: Regular henna applications can lead to product buildup on the hair, which may affect its overall health by. Buildup can clog the hair follicles and potentially interfere with healthy hair growth.
To mitigate these risks, consider the following:
Moderation: If you choose to use henna, use it in moderation and avoid frequent applications to prevent excessive protein buildup.
Deep Conditioning: Incorporate deep conditioning treatments into your hair care routine to maintain moisture balance and counteract the potential drying effects of henna.
Consult a Professional: If you experience any adverse effects or concerns about hair thinning or balding, consult a professional hairstylist or dermatologist for personalized advice and solutions.
Ultimately, individual hair types and sensitivities can vary greatly, so it's essential to listen to your hair's needs and adapt your hair care routine accordingly. If henna or any other hair product is causing issues, it may be worth exploring alternative options that better suit your hair type and goals.
