Procter & Gamble shampoos occupy 20% of the global market share, of which Head & Shoulders is the best-selling shampoo brand, selling 110 bottles per second in the global market and selling 29 million bottles throughout the year. In 2013, it won the first place in China's cleaning and care market with a market share of 17.5%.
 
It is indisputable that Head & Shoulders has made pioneering feats in the field of dandruff, such as the development of ZPT, the most widely used anti-dandruff ingredient at present, but the formula of its main product is too simple. The anti-dandruff ingredient has and only ZPT, and the most irritating sodium lauryl sulfate SLS is added to the surface, which is placed on the scalp that is prone to flaky and easy breakage, which is not very safe, and long-term use may damage the scalp barrier.
 
There is little difference between the products of the same series, and the difference is mainly due to the fine-tuning of ingredients and different fragrance types. Ocean Vitality is also currently the most popular popular fragrance for the masses, with a cool smell and a very successful simulation of the deep sea. On the whole, the anti-dandruff power of Head & Shoulders products is not bad, but the long-lasting moisturizing power and mildness are not good. However, due to its wide distribution, the price is not expensive (200ml is priced at 28 yuan), which is suitable as an alternative to daily shampoo.
