How to choose shampoo? Look at your scalp first, not just for dry or oily hair
Oil control, moisturising or colour-safe? Choose by scalp condition, how often you wash, your colour and perm history and how you style hair.
When choosing a shampoo, you should first look at what needs to be cleaned on your scalp, and then look at how to take care of dyed and permed hair. People whose scalp is prone to oiliness but whose hair ends are dry due to bleaching and dyeing may need to separate cleansing and hair care, instead of just looking for a bottle "for oily hair".
First observe the condition after washing and the next day
Do you feel tight or itchy after washing? Does it feel greasy and flat the next day? Do you feel like your styling products cannot be washed clean? Keeping records will tell you a better fit than just looking at the product name.
Is the stronger the cleaning power, the better?
If you feel very astringent after vigorously removing oil, it does not mean that your scalp will be healthier after washing it. Water temperature, dosage, cleaning gestures and rinsing time will all affect the results; people who frequently use styling products can also adjust according to their needs instead of washing them multiple times every time.
Why should we consider color protection after dyeing?
If you want to delay the color change after dyeing your hair, you can choose color care products according to the tone. However, the scalp still needs to be cleaned normally, and color-replenishing shampoo should not be used as the only hair shampoo product for a long time.
Which bottle should I buy if I have scalp problems?
For persistent redness, swelling, heavy scaling, pain, or obvious hair loss, you should not just rely on changing shampoo brands. It is recommended to seek professional evaluation such as dermatology.

Product selection needs to be adjusted based on individual scalp, frequency of use and dyeing and perming conditions.
