Why does solid shampoo give me dandruff and itching?

The scalp is the mirror of healthy hair. A scalp that scratch and gives you dandruff are all signs that reveal his poor state of health. But then, How can I explain that my scalp itches when I use my solid shampoo?

The regulation of the scalp is complex. The natural hair oil called sebum, is its natural barrier against external aggressions (sun, pollution, chlorine, etc.). However, liquid shampoos have always attacked your scalp. Indeed, the chemical agents contained in the latter, such as sulphates, allow the base to wash the scalp. However, they are also partly responsible for its dysregulation because they are very aggressive surfactants which act as a stripper on the latter. The disorder of the scalp by these products thus causes dandruff and itching.

So how do you explain that it is when you switch to a solid shampoo that dandruff and itching appear? 

The appearance of dandruff and itching is due to a capillary transition that disrupts the balance of the scalp. When you go over a solid shampoo, the scalp is cleansed with all new, much gentler components. He therefore knows again a whole new hair routine, which will sometimes upset the balance of the scalp and make it scaly. Indeed, even if the surfactants are softer and attack much less, the sudden change in composition when you switch to solid shampoo can give you dandruff and itchy scalp. This doesn't mean that solid shampoo is bad for you. Above all, your scalp will need to get used to the new shampoo and go through the hair transition period.

It is still important to determine where your dandruff and itchy problem is coming from by using a strong shampoo. This can come from improper use of the latter during your wash. But also shampoo that does not suit you for different reasons. 

Solutions for itch and dandruff problems using your solid shampoo

We are now going to help you remove this urge to scratch yourself by adopting certain gestures and habits when you make your solid shampoo. If the itching and dandruff persist, we will give you advice on how to change your solid shampoo, while respecting certain criteria related to the composition of the latter. 

Solid shampoo that causes dandruff and itching: take the appropriate steps to avoid it

To remedy this problem of itching and dandruff, here are some tips to help you get through the hair transition period and prevent your scalp from itching.

• Lather your solid shampoo in your hands rather than applying it directly to the scalp. You risk using more solid shampoo than necessary and damaging the scalp with friction movements. This will also prevent you from leaving shampoo shavings on your scalp and creating a reactive itch.

• To prevent your solid shampoo from giving you dandruff, you can alternate the first few weeks between a liquid shampoo and your new bar shampoo. In this way, the hair will have time to get used to the new components and the hair transition will be easier to go through.

• Rinse thoroughly your solid shampoo to keep it from scratching. If you do not not rinse properly, solid shampoo can stick to your scalp, suffocating it and so cause itching and give you dandruff.

• Rinse your hair with vinegar as a last jet! Dilute it beforehand with lukewarm water. This trick helps to get rid of irritating and drying limescale remains. Plus, it will decrease the chances of your solid shampoo giving you dandruff.

• If your solid shampoo gives you dandruff, only shampoo once per wash. No need to repeat it 2-3 times! You risk stripping more than washing the hair by applying it excessively. As a result, you will unfortunately tend to make your scaly scalp.

• If your head is itching from the solid shampoo, it is best to brush your hair regularly. This will sanitize the scalp and clean the dust. In addition, you will remove the last residues of solid shampoo which can be responsible for itching and dandruff.

• A itchy scalp can also be a sign that it is dry. Moisturize them with vegetable oils such as castor oil, coconut oil or jojoba oil. Perform this treatment once a week before your shampoo. Be careful not to apply too much of it either! You risk choking your roots and creating itchy rashes and dandruff.

Find the right solid shampoo for an itchy scalp

Si you come to the end of the hair transition period and that despite these gestures, your solid shampoo always gives you dandruff and is itchy, it may not be right for you. To find the solid shampoo that's best for your scaly scalp problem, here are some tips: 

• Choose a strong shampoo that is suited to your hair type to avoid itchy scalp. Solid shampoos have different formulations and each corresponds to hair types, since they require special and personalized care. It is therefore essential that you respect your hair type to have a healthy scalp.

• Choose solid shampoo with essential oils (HE) special to sanitize and avoid itching problems. We recommend the essential oils of tea tree, Roman chamomile or lavender. Be careful because some people do not tolerate ET and they can then be responsible for a scaly scalp. If the solid shampoo you are using contains essential oils and causes you itching or dandruff, try one that does not.  

• Preferably choose a mild solid shampoo that will soothe your scalp if it gives you dandruff.. This is because some surfactants are aggressive, while others are formulated to be mild.

To help you when choosing your solid shampoo, here are the mild and very mild surfactants to favor. Decyl Glucoside, Coco Glucoside, Disodium Cocoyl Glutamate or Lauryl Glucoside, Sodium Coco Sulfate, Sodium Cocoyl Isethioniate, Cocamidopropyl Betaine, Disodium Cocoamphodiacetate, or Disodium Laureth Sulfosuccinate. 

On the contrary, certain surfactants should be avoided because they are aggressive for your scalp. They can be itchy and give you dandruff. These are Sodium Lauryl Sulfate, Sodium Laureth Sulfate, and Ammonium Lauryl Sulfate.
