If you've ever taken a chemistry class, then you’ve probably heard of the PH scale before.
However, many do not know that if you wish to maintain that vibrant color, shine and overall health of your hair, it is essential to know how the PH levels in your shampoo can affect it.
Shampoo is an essential part of everyone's hair care routine. It helps us keep our hair clean, nourished and healthy. But have you ever wondered why the shampoo you use sometimes doesn't work as effectively as it should? The answer could lie in the pH level of your shampoo.
In this article, we will discuss how the pH level of your shampoo can affect your hair and why it is important to choose a shampoo with the right pH level for your hair type.
What is a PH scale?
pH stands for "potential of hydrogen" and is a way to measure the acidity or alkalinity of a substance on a scale of 0 to 14.
A pH level below 7 indicates acidity, while a pH level above 7 indicates alkalinity. 7 is neutral.
The pH level of a substance is determined by the concentration of hydrogen ions (H+) in it. The more hydrogen ions present, the lower the pH level and the more acidic the substance will be.
On the other hand, substances with a higher concentration of hydroxide ions (OH-) will have a higher pH level and are considered alkaline.
It is important to note that the pH scale is logarithmic, meaning each number on the scale represents a tenfold difference. For example, a substance with a pH level of 4 is ten times more acidic than one with a pH level of 5 and one hundred times more acidic than one with a pH level of 6.
What is the PH of hair
The ideal pH level for hair is slightly acidic, ranging from 4.5 to 5.5.
This is because human hair has a natural protective layer called the cuticle, which is made up of overlapping layers of flat cells that act as a barrier against external stressors.
When the pH level of your hair falls within this range, the cuticle layer remains flat and smooth, keeping the hair shaft strong and preventing damage. However, when the pH level is too high or too low, the cuticle layer becomes raised and damaged, making the hair more prone to breakage, frizz, and other issues.
The natural pH level of hair can also be affected by various factors such as genetics, age, hormonal changes, and environmental factors like pollution and hard water. Additionally, the use of hair styling products, chemical treatments, and even water temperature can alter the pH level of your hair.
How the PH of your shampoo affects your hair
Now you may be wondering, how does the pH level of your shampoo affect your hair? The answer lies in the fact that shampoos are alkaline by nature. This is because most cleaning agents used in shampoos, such as surfactants, are alkaline substances.
When you use a shampoo with a high pH level on your hair, it can cause the cuticle layer to swell and open up, leading to damage and loss of moisture.
On the other hand, when you use a shampoo with a low pH level, it can cause product buildup on the scalp and hair, making it appear dull and lifeless.
It is crucial to choose a shampoo with a pH level that is close to your hair's natural pH level. This will help maintain the health of your hair, prevent damage, and keep it looking shiny and smooth.
Different types of shampoos
There are various types of shampoos available in the market, and each has a different pH level. Some popular types include:
Clarifying shampoos: These have a high pH level and are designed to deeply cleanse the hair by removing product buildup and excess oils.
Moisturizing shampoos: These have a lower pH level and are suitable for dry or damaged hair as they help retain moisture.
Color-safe shampoos: These have a pH level similar to that of human hair and are specifically formulated to protect color-treated hair from fading.
Anti-dandruff shampoos: These typically have a high pH level and contain active ingredients like zinc pyrithione or salicylic acid to target dandruff and scalp issues.
Sulfate-free shampoos: These have a lower pH level and do not contain harsh sulfates, making them gentler on the hair and scalp.
It is important to choose a shampoo that matches your hair's natural pH level. Using a shampoo with a significantly different pH level can disrupt the balance of your hair and lead to various issues.
I love using the Volume Shampoo as my clarifying shampoo for my clients in the salon. It uses bentonite clay to pull out impurities and infuse the hair with a ton of moisture.
What is the ideal PH of shampoo
The ideal pH level of shampoo varies depending on your hair type and the current condition of your hair. Generally, shampoos with a pH level between 4.5 to 5.5 are considered suitable for all hair types.
For individuals with oily or fine hair, using a slightly higher pH level shampoo (around 6 or 7) can help remove excess oil and add volume to the hair. On the other hand, those with dry or damaged hair may benefit from a lower pH level shampoo (around 4 or 5) as it will be more gentle on their hair.
Additionally, if you have color-treated hair, using a color-safe shampoo with a pH level similar to your hair's natural pH can help maintain the vibrancy of your hair color.
It is also important to keep in mind that using a shampoo with a drastically different pH level than your hair's natural pH can cause the cuticle layer to become raised and lead to damage. Therefore, it is best to choose a shampoo with a pH level closest to your hair's natural pH.
The Moisture Shampoo is sulfate free and keratin and color safe. This is great for hydrating and nourishing chemically treated hair while preventing fading.
How does the PH level of shampoo affect curly hair health
Now you have a better understanding of the pH scale, hair's natural pH level, and different types of shampoos available. But how does all this information apply to curly hair?
Curly hair has a unique structure that makes it more prone to dryness, frizz, and damage. The tight curls make it difficult for natural oils to travel down the hair shaft, leaving curly hair more susceptible to moisture loss and damage.
Choosing the right shampoo with a suitable pH level is crucial for maintaining the health of curly hair. Using a high pH level clarifying shampoo can strip away too much of the natural oils, leaving curly hair even drier and frizzier.
While using a low pH moisturizing shampoo can help retain moisture in the hair and keep it looking healthy and defined.
Additionally, us with curly hair should also be more mindful of the ingredients in our shampoos. Harsh sulfates, alcohol, and other drying ingredients can further damage curly hair. It is best to opt for sulfate-free shampoos with natural oils or humectants that can help nourish and hydrate curly hair.
Mistakes to avoid when it comes to shampoo and hair PH
Now that you know the importance of maintaining the right pH balance for your hair, here are some mistakes to avoid:
Using harsh shampoos: Using a shampoo with a high pH level can cause damage to your hair. Avoid using clarifying shampoos too frequently and opt for more gentle options that are suitable for your hair type.
Not considering hair type: Not all shampoos are created equal, and what works for one person may not work for another. Consider your hair type and condition when choosing a shampoo to ensure it matches your hair's natural pH level.
Overlooking product buildup: Using products with different pH levels can lead to buildup on the scalp and hair. This can cause issues like dryness, dullness, and even dandruff. Make sure to regularly clarify your hair or use a clarifying shampoo to remove any buildup.
Ignoring the condition of your hair: Your hair's pH level may change depending on its current condition. For example, if you have colored your hair, it may have a slightly different pH level. Consider the current state of your hair and choose a shampoo accordingly.
Using hot water: Washing your hair with hot water can raise the cuticle layer and disrupt the natural pH balance of your hair. Stick to lukewarm or cool water when washing your hair to prevent damage.
By avoiding these common mistakes, you can maintain the right pH balance for your hair and promote its overall health. Remember to pay attention to the ingredients and pH level of your shampoo, as well as the specific needs of your hair type. With the right approach, you can keep your hair looking healthy and beautiful!
How to check the PH of a shampoo
The pH level of a shampoo can greatly affect its effectiveness and impact on your hair. If you are unsure about the pH level of your current shampoo or want to check if a new one is suitable for your hair, here's how you can do it:
First, you will need pH strips or a pH meter, which can be easily found at most drugstores or online. Follow these steps to check the pH level of your shampoo:
Dilute a small amount of shampoo in a cup of water (around 100 ml). Make sure it is well-mixed.
Dip the pH strip or meter into the shampoo mixture.
Remove the strip or meter and wait for a few seconds until the color changes.
Match the color on the strip to the pH scale provided with the strips. For meters, simply check the digital reading.
A pH level between 4.5 to 5.5 is considered ideal for most hair types, as it is similar to the natural pH level of hair. However, if your hair is oily or fine, a slightly higher pH level (around 6-7) may be more suitable. On the other hand, if you have dry or damaged hair, a lower pH level (around 4-5) can help prevent further damage.
If the pH level of your shampoo falls outside of this range, consider switching to a different shampoo that is more suitable for your hair type. It's also important to note that the pH level may vary between different brands and types of shampoos, so it's always a good idea to do this test with any new shampoo you try.
Is a shampoo's pH level the only factor to consider?
The pH level of a shampoo is an important factor to consider, but it's not the only one. There are other factors that can affect how a shampoo works on your hair.
As mentioned earlier, different hair types may require different pH levels in their shampoo. Additionally, the overall health and condition of your hair can also impact how it responds to certain shampoos. For example, if your hair is damaged or chemically treated, it may require a shampoo with a lower pH level to prevent further damage.
The ingredients in a shampoo can also play a significant role in how effective it is for your hair. Some people may have sensitivities or allergies to certain ingredients, so it's important to check the ingredient list and avoid any potential irritants. Additionally, natural oils and humectants in a shampoo can help nourish and hydrate curly hair, making it more manageable and healthy.
The frequency of washing your hair can also affect its pH balance. Constantly using harsh shampoos or over-washing your hair can strip away too much of the natural oils, leading to dryness and damage. It's important to find a balance and listen to your hair's needs when it comes to washing.
Lastly, other hair care products like conditioners and styling products can also impact the overall pH level of your hair. It's important to choose complementary products that work well together to maintain a healthy pH balance for your hair.
