When choosing shampoo, you should start with your own needs. For example, people with oily hair, long hair, or those who work in relatively dirty jobs need to focus on cleaning. For oily hair, if the hair is not very dirty but very dry, you can use a mild shampoo for dry hair; if you have dandruff, it is best to use an anti-dandruff shampoo. For people with long hair that is difficult to comb, it is still a good choice to use a silicone shampoo, or use a silicone-containing conditioner or hair essence after shampooing, but be careful not to apply it on the scalp; if you have less hair, fine hair, or a scalp that is prone to oiliness and sensitivity, it is recommended to use a silicone-free shampoo, which can make your hair fluffy, look more voluminous, and your hair and scalp will be more refreshed. For those who are worried about silicone oil deposits on the scalp, or those who have sensitive scalps but want smooth and easy-to-comb hair, they can use silicone-free shampoo with silicone-containing conditioner or hair essence, because the conditioner or essence can be applied only to the hair and hair ends, which does not involve the scalp and can avoid the risks of silicone oil. In short, it does not mean that products containing silicone oil are necessarily bad, but that products containing silicone oil may have some potential problems. Consumers should look at and choose products that are suitable for them rationally.
