Everyone knows how to wash their hair: just apply shampoo, rinse thoroughly, condition, and wash again. However, even after following these steps, many people still find that their hair ends are dry and brittle, while their scalp quickly becomes greasy. Recently, a hair salon in New York caused a stir in the beauty world when it "uncovered" a new shampooing technique that helps hair become as clean and shiny as possible. The method is called by the intriguing name: "sandwich shampooing."
The sandwich shampooing method first appeared in New York hair salons and quickly spread across TikTok. What made this technique famous was not only its interesting name but also its practical effectiveness: it makes hair shinier, keeps color longer, and limits damage after each wash. The principle behind this technique is very simple: adding a layer of conditioning or protective product between shampooing steps, like sandwiching filling between bread, to reduce irritation from detergents and limit water damage to the hair shaft.

The sandwich-style shampooing method is ideal for those seeking a balance between cleansing the scalp and deeply moisturizing the hair shaft. It is a "lifesaver" for hair that is oily at the roots but dry and brittle at the ends—a common condition that makes it difficult for many people to choose the right product. Thanks to the conditioner applied beforehand, weak and easily damaged hair strands are maximally protected during washing without causing stickiness at the roots. |  |

People who have dyed or bleached their hair also benefit significantly. Applying conditioner before shampooing helps limit excessive cuticle expansion and reduces color fading. For curly or wavy hair, the sandwich method is even more effective. The "sandwiched" conditioning layer helps lock in moisture better, reduces frizz, and supports natural curl retention, resulting in softer, more defined curls. |

A secret to achieving shiny, smooth hair was unexpectedly discovered at a hair salon in New York.
In short, if you're craving hair that's shinier, softer, and more vibrant than ever, this smart shampooing method could be the secret to completely transforming your hair!
Gội đầu kiểu “sandwich” là kỹ thuật gội mới được các stylist tại New York giới thiệu, giúp mái tóc vừa sạch sâu vừa giữ được độ mềm mượt. Thay vì thực hiện theo quy trình gội – xả thông thường, phương pháp này áp dụng nguyên tắc “nhiều lớp”, tương tự như các lớp của một chiếc sandwich.
Everyone thinks that shampooing is a very familiar and simple task: just wet your hair, apply shampoo, massage gently, then rinse thoroughly, followed by conditioner and another shampoo to finish. However, in reality, even after following all these steps, many people still find that their hair is not thoroughly clean, the ends are dry and brittle, and lack smoothness, while their scalp becomes greasy after just one day. This confuses many people and makes them think their hair is "difficult to care for," but the real reason is that they are not shampooing correctly.
Recently, a famous hair salon in New York caused a stir in the beauty community when it introduced a completely new shampooing technique, researched based on hair fiber structure and the natural oil secretion mechanism of the scalp. This method not only cleans more effectively but also helps hair become softer, shinier, and healthier, while minimizing damage caused by friction during shampooing. This method has been given a fun and memorable name: "Sandwich shampooing".
The name comes from the fact that the steps are divided into "layers," alternating between shampoo and conditioner like the layers of a sandwich. Alternating the products in layers helps thoroughly cleanse the scalp while continuously protecting the mid-lengths and ends from harsh washing. As a result, hair retains its natural moisture, preventing dryness, breakage, and significantly reducing oiliness.
Not only does this method leave hair soft and smooth, it is also suitable for those with dyed, permed, or dry hair – groups that are easily damaged when exposed to the detergents in shampoo. "Sandwich shampooing" is quickly becoming a new trend, highly rated by many hair experts and recommended for damaged or weak hair.
