When it comes to hair products and hair care generally, one very important thing you have probably ignored is the pH level. Many folks invest in different hair products without fully understanding the importance of pH, or bothering to find out the pH level of these products.
Now, if you’re unsure about the pH concept, don’t worry—you’ll understand the entire concept as you read along.
pH, which stands for “potential of hydrogen,” measures a substance’s acidity or alkalinity. The pH scale runs from 0 to 14, where 7 is neutral. Values below 7 are acidic, and those above are basic or alkaline. By understanding the pH scale, you can alter the pH of cosmetics like hair products when needed.
The pH level of hair products plays a pivotal role in maintaining the health and vitality of our hair. In this guide, you will learn about pH balance, its importance for hair health, and how pH-balanced hair products can benefit different hair types. Additionally, we will provide recommendations for pH-balanced shampoos, conditioners, and styling products to help you achieve your hair goals.
Importance of pH Balance for Hair Health
The hair’s natural pH level typically falls between 4.5 and 5.5, making it slightly acidic. This acidity is crucial for maintaining the structure and health of the hair shaft, as it helps to seal the cuticle layer and retain moisture. When the pH of the hair is disrupted, whether by harsh chemicals, environmental factors, or unsuitable hair products, it can lead to various issues such as dryness, frizz, breakage, and even scalp irritation.
Hair is extremely sensitive to the pH level of products applied to it. Maintaining the hair’s natural pH balance is essential for preserving its strength, elasticity, and overall health. When the pH of hair products is too high (alkaline), it can cause the hair cuticle to swell, leading to moisture loss and increased susceptibility to damage.
On the other hand, overly acidic products can cause the cuticle to contract excessively, resulting in a rough, frizzy texture. This is why it is important to check the pH of hair products, if possible, particularly those used when the hair cuticle is hydrated. If you use the wrong shampoo, for example, when the hair is wet, it can enter the cuticle scales, affecting the structure and, in severe cases, cracking the fiber axis w, which leads to breakage.
By using pH-balanced hair products, which closely match the hair’s natural pH level, you can help keep the cuticle layer smooth and intact, thus preventing moisture loss and damage.
Some Common Hair Products/Chemicals and their pH range
Make it a habit to always check the ingredients list of any hair product you purchase. When you do, sometimes you’ll be surprised that some of these products contain certain chemicals that cause your hair to sway out of its healthy pH range. You may also see other beneficial ingredients for your hair as they have a healthy pH level.
Overall, you should be equipped with the right knowledge to know exactly what you’re putting into your hair and how it affects it.
Below are some common hair products/chemicals and their pH ranges:
- Hair Dyes (permanent): 9.5 – 10.5 (alkaline)
- Hair Dyes (semi-permanent): 7 – 9 (alkaline)
- Hairspray: 8 – 10 (alkaline)
- Bleaching & Highlights: 10 – 11 (alkaline)
- Perm Treatment: 8 – 9 (alkaline)
- Baking Soda: 8 (alkaline)
It is important to avoid these products, especially those with a pH level greater than 13, as they can cause extreme damage to the scalp, hair, and surrounding skin.
Benefits of pH-Balanced Hair Products
Restores Moisture Balance
One of the hair’s most important need is moisture. pH-balanced hair products help maintain the hair’s natural moisture balance, preventing it from becoming dry and brittle. This is especially beneficial for individuals with dry or damaged hair, as it helps to improve hydration and softness.
Seals the Cuticle
By matching the hair’s natural pH level, pH-balanced products help to seal the cuticle layer, creating a smooth surface that reflects light and enhances shine. This can result in smoother, more manageable hair with reduced frizz and flyaways.
Prevents Scalp Irritation
An unbalanced pH in hair products can cause irritation and inflammation of the scalp, leading to discomfort and potential hair loss. pH-balanced formulas are gentler on the scalp, reducing the risk of irritation and promoting a healthier environment for hair growth.
Enhances Color Retention
For those with color-treated hair, maintaining the hair’s pH balance is essential for preserving the longevity and vibrancy of the color. pH-balanced products help to seal the cuticle and prevent color molecules from escaping, resulting in more vibrant, long-lasting color.
Healthy Scalp and Hair
The scalp’s pH balance helps keep it healthy. An imbalanced pH can lead to issues like dandruff, dryness, or excessive oiliness. pH-balanced hair products also help keep the cuticle layer of the hair smooth and flat, which contributes to shine and manageability.
Color Retention
For those who color their hair, pH balance is essential for the longevity of the color. An imbalanced pH can cause the color molecules to become unstable and quickly fade.
Damage Prevention
Maintaining the correct pH balance can help prevent damage to the hair shaft, such as breakage and split ends.
Product Efficacy
Hair care products, like shampoos and conditioners, are formulated to work optimally at a certain pH level. Using products with a pH that matches the hair’s natural acidity ensures they can effectively cleanse, moisturize, and protect the hair.
Overall, maintaining the pH balance of the hair helps to keep it looking and feeling its best, while also supporting overall scalp health.
How To Identify pH Levels In Hair Products
Unfortunately, you may not be able to get the pH level of hair products from the packaging labels. However, you can find out on the brands’ websites, as some brands disclose this information only on their websites. Some companies choose to do otherwise. You can also contact them directly, asking them to disclose this information. As a last resort, you can purchase a pH test online; some are very simple.
Recommendations for pH-Balanced Hair Products
Here are some recommendations for pH-balanced hair products including shampoos, conditioners, and styling products:
Shampoos
Some shampoos you can get without having to worry about the pH level include Aveeno Pure Renewal Shampoo, SheaMoisture Coconut & Hibiscus Curl & Shine Shampoo, OGX Hydrating + Tea Tree Mint Shampoo, and Neutrogena Anti-Residue Gentle Clarifying Shampoo.
