When it comes to achieving and maintaining healthy hair, there are many factors to consider. One often overlooked aspect is the role of pH and enzymes in hair care. Understanding how pH and enzymes affect our hair can help us make better choices when it comes to products and treatments.
Let's start with pH. pH, which stands for potential hydrogen, measures the acidity or alkalinity of a substance. Our hair has a natural pH range of 4.5 to 5.0, which is slightly acidic. This pH range is important for the overall health and strength of our hair.
Mildly acidic hair care products can be applied to the hair to harden the outer layer, flatten the cuticles, and shrink the diameter of the hair strands. This results in hair that is glossy, shiny, and less prone to tangling and snagging on adjacent strands. Additionally, hair that is close to its ideal pH range is at its peak strength, making it more resilient and less prone to damage.
On the other hand, alkaline products have a higher pH and can cause the hair to swell. This leads to the lifting of the cuticle and the removal of natural oils from the hair. The end result is frizzy, dull, and brittle hair that is prone to breakage and tangling. In extreme cases, highly alkaline solutions can break down the disulfide bonds between the keratin protein molecules that make up our hair, ultimately dissolving the protein. This is why alkaline solutions are commonly used in hair treatments such as perming or relaxing, but they can be extremely damaging, especially for already fragile hair.
Fortunately, most modern shampoos and conditioners are formulated to be slightly acidic, with a pH range similar to that of the hair's natural acid mantle. This pH range of 4.0 to 5.0 helps to maintain the health and balance of our hair. If you take a closer look at the ingredient list of your hair care products, you may notice chemicals such as citric acid, sodium hydroxide, or triethanolamine, which are used to adjust the pH and ensure that the product is within the desired range.
Moving on to enzymes, they are often referred to as the catalysts of life. Enzymes are proteins secreted by cells that facilitate chemical reactions in our bodies. They act as catalysts, inducing changes in other substances without undergoing any changes themselves. Enzymes can be found throughout our bodies, and their presence is essential for various biological processes.
In the context of hair care, enzymes play a crucial role in maintaining the health and vitality of our hair. Hair is primarily composed of a protein called keratin, and enzymes are responsible for the production and maintenance of this protein. Specifically, the enzymes present in our hair are designed to build keratin protein from amino acids and nothing else. This ensures the strength and structure of our hair strands.
Enzymes are also important for the digestion of food. For example, amylase, an enzyme found in our saliva, initiates the breakdown of carbohydrates. Another well-known enzyme is lactase, which breaks down lactose, the sugar found in milk. If you experience discomfort after consuming milk, it may be due to a lack of lactase enzyme. Without an adequate supply of the appropriate enzymes, the benefits of vitamin and mineral supplementation can be diminished, as enzymes are necessary for the utilization of these nutrients.
The speed and efficiency of cellular reactions and chemical processes in our bodies are greatly enhanced by enzymes. They act as catalysts, speeding up reactions by hundreds of thousands of times compared to reactions without enzymes. This acceleration is crucial for various physiological functions, including the growth and repair of our hair.
In conclusion, maintaining the proper pH balance and understanding the role of enzymes are essential for achieving and maintaining healthy hair. By using slightly acidic hair care products that align with the natural pH of our hair and ensuring an adequate supply of the appropriate enzymes, we can promote shiny, strong, and resilient hair. So next time you're shopping for hair care products or considering a hair treatment, remember to pay attention to the pH and the potential presence of enzymes to give your hair the care it deserves.
