2021.7.19Introducing the correct method to shampoo hair

Even though I make sure to shampoo my hair everyday, as well as practice proper hygiene, why does my head still feel itchy…
Have you had that experience before? There are a variety of reasons as to why itchy scalp occurs; the combat methods are also depending on the situation. Here we will match the causes with ways you may tackle it, and explain the correct way to shampoo your hair.


[ Causes of Itchy Scalp ]

– Residue of Sweat and Dirt etc.
Despite making sure to wash my hair, it still feels greasy and itchy (scalp). For those who feel this way, when shampooing your head do you only wash your hair? If you don’t properly wash your scalp as well, the buildup sweat and dirt throughout the day are left behind as it is. This can cause itchiness of the scalp.

– Overproduction of Sebum
The problem of sebum overproduction comes from insufficient hair washing or natural oily skin(/scalp). Due to the excessive sebum clinging onto the scalp, a breeding ground for bacteria, it can result in dandruff.

– Barrier Function Reduced Due to Dryness
Contrary to the previous point, over-washing or naturally dry skin(/scalp) can result in the skin barrier losing its vitality due to the dry conditions. Using shampoos that are too harsh tend to strip too much moisture, and more sebum than necessary, leaving the scalp dehydrated and itchy. Similar to how you have to choose the right skincare for your face’s skin type, it is important to choose the right shampoo that suits your hair and scalp as well.

– Exposure to Ultraviolet (UV) Rays
The cause of many problems during the summer. We take extra care to protect our face and arms from the damaging UV rays. However, our scalp and hair unprotected are also prone to the same kind of damage. It is of equal importance to have adequate protection to the scalp and hair as well.

– Wrong Washing Technique
Not properly pre-rinsing the hair before shampoo, not washing the scalp, and even over rinsing the hair after shampooing. Washing your hair wrongly can lead to the scalp being easily irritated. The next segment will introduce correct methods of hair washing where you may assess for yourselves which will suit you best.

– Atopic Dermatitis etc.
In the case where it is not just itchiness, and it is accompanied with symptoms such as slight redness and swelling, dandruff, and soreness/pain; there is a possibility that it is not due to the shampoo method, but rather a different issue lurking beneath the surface. Especially if it was relatively discovered after hair dyeing or perming, it is recommended to visit the nearest dermatologist for a medical exam.

[ Proper Ways to Wash Your Hair ]

– Choosing Less Harsh Shampoos
Usage of the wrong choice of shampoo cleansing strength that doesn’t match your hair and scalp is one of the reasons that can be deduced from hair troubles. With the growing popularity of organic products in the recent years, silicone-free, additive-free, and natural ingredients only, there are many of such gentle products widely available in the market. We recommend considering a change to these products without harsh cleansing agents and soothe that irritated scalp.

– Pre-rinsing the Hair
Make sure to rinse with warm water before washing your hair with shampoo. The best way to do this would be to throughly rinse your head under 37-38°C water, effectively removing any dust etc. clinging on the hair and scalp. We are able to cleanse a reasonable amount of dirt off the head with just this one step alone.

– Massaging the Scalp
Whilst washing your hair, massage the scalp as gently as possible using your fingertips. As you do this repeatedly, to get as much residue off as possible, be sure not to use your fingernails to scrub the scalp in the process. The hair should also not be scraped (by the fingernails) whilst washing. Instead, let the bubbles ‘glide’ over it in order to cleanse the hair of any buildup.

– Thoroughly Rinsing off Shampoo
After washing the scalp and hair, be sure to rinse off the shampoo, along with the effectively lifted residue, out of the hair. Please ensure more care is taken in doing this as compared to the pre-rinsing before shampooing. The estimated time spent on this step should be roughly twice the amount taken for washing the head.

– Blowdrying the Hair until 80-90% Dry
You might think that it is best to blow dry the hair until the ‘damp’ feeling is completely gone. However, the ideal finish should be drying it until it is about 80-90% dry, leaving it with just the slightest amount of dampness. It is crucial to note that over-blowdrying the hair will create frizz. Please make sure to adequately dry your hair such as to prevent bacteria from propagating on the scalp.


[ There are Two Types of Dandruff! ]

– Dry Dandruff Due to Dry Scalp
Scalp problems are usually itching, together with the tendency of flaking: dandruff. The root of scalp dryness appears in the form of patchy flaking across the entire scalp and can be categorised as dry dandruff. Dry scalp disrupts the skin cell renewal rate, in turn causing premature keratin loss.

– How to Counteract Dry Dandruff
One of the reasons dry dandruff appears is due to the harsh cleansing power of the shampoo in use. Avoid using products that contain combinations of lauryl sodium sulfates and surfactants (surface-acting agents), and instead opt for gentle cleansing shampoos.

– Oily Dandruff • Scales Due to Seborrheic Dermatitis
Oily dandruff can be a result of insufficient washing of the scalp, or naturally oily skin. Symptoms usually appear during periods of high humidity, especially from rainy seasons to the summertime.

– How to Counteract Oily Dandruff
As overstimulation of the scalp can result in symptoms of this condition to deteriorate further, likewise for dry dandruff, it is also recommended to use gentle shampoos. You may also keep an eye out for products that contain anti-bacterial and anti-fungal ingredients as they are also effective in combating oily dandruff.

[ Methods to Deal with Itchy Scalp ]

– Making the Change to Gentle Shampoos
When trouble occurs in the scalp, the shortcut to abating it is to reduce the stress directed there as much as possible. It will be good to select additive-free, gentle cleansing shampoos.

– Usage of Scalp Care Lotion and Oil
Instead of focusing on just the type of shampoo, consider products such as lotions and oils that are formulated for scalp care. Usage of these, on top off the right shampoo, is recommended as well. The lotion provides additional moisture to the dry scalp, while the oil acts as a seal to lock in the moisture.

– Visit a Dermatologist
Despite doing all that you can to fix the problem, the itchiness does not go away. In this situation, it is best to see a dermatologist to get a professional diagnosis. Getting a medical exam done will help you understand the condition of your scalp and hair better. You can also find out information to take note of, with regards to your future lifestyle, as well as advice on what shampoo and cosmetic products that suit you best.
