About 50% of people occasionally or regularly suffer from an itchy or irritated scalp. Most complaints often already exist (recognised or not) and are aggravated by the use of hair products, describes Dermatologist Harma Stenveld. The complaints are almost never caused by the use of certain hair products, but they already exist and are aggravated by contact with cosmetics. 

Scalp problems and the CG method

As indicated, the irritation is often not processed by hair care alone. However, many products can really irritate the scalp. Most irritations are often caused by products that you do not have to rinse out. Think of a leave-in, gel or other products that you apply to your hair without rinsing it out. 

Rinse-out products such as a shampoo or conditioner often cause fewer problems because the contact moment is shorter than products that you do not have to rinse out.

Dandruff or a dry scalp

In other words, dandruff is also a watering infection. It is sometimes difficult to distinguish from a dry scalp because both can cause flakes. Dandruff can often be distinguished because the flakes are fatter and clump together more. 

With a dry scalp you often recognize that the dryness is also noticeable in other parts of the body. That is not the case with rose. 

hair loss

After the menopause, sebum production decreases in women. This makes the (scalp) skin drier and itching can occur more quickly. In addition, the decreasing sebum production can also result in hair loss. 

Hair loss is an increasing problem. Always go to the doctor if you have persistent complaints. Possible causes of hair loss are iron deficiency, abnormal hormone levels or a thyroid problem. You can therefore ask your doctor to perform a blood test. 


Do you immediately get itchy from a product as soon as you use it? Then put him aside right away! And then rinse your hair with a shampoo that your skin can tolerate. It is advisable to stop using the product. 

Perfume in hair products can cause irritation and itching of the scalp. In addition, ingredients in hair dyes such as PPD (paraphenylenediamine) can cause extreme irritation. This ingredient is mainly found in hair dye. An allergy to PPD is rare, but in case of itching it is therefore wise to inform your hairdresser that you want a hair dye without PPD. 

Henna paint is often recommended. But make sure you are also critical when choosing Henna paint. You can always dye your hair with natural Henna. But there are also variants that do contain PPD. 

Water and its effects on your scalp

Did you know that water and a sensitive scalp also go bad together? Water can increase the PH value, making your dry scalp even drier. If you have a sensitive scalp, use a mild shampoo and use lukewarm water when washing. 

Stress and the consequences for your scalp

Itching, eczema and hair loss can also be caused by stress. Do you suffer from 1 of these complaints? This can then cause even more stress, which can aggravate the complaints. 

Dermatologists advise in case of stress and/or in combination with hair loss to also look at a healthy diet. Eat alternately and make sure you have enough healthy fats. Getting enough sleep per night can also reduce stress.
