Slicked-back hair

What it is

The style consists of medium-length hair, typically five to seven inches long, combed flat against the scalp. The hair is directed straight back over the crown or parted centrally or to the side. The finish is high-gloss and smooth, often described as helmet-like due to its rigid, flattened appearance. It was the dominant look for men during the 1920s, worn both under hats and when bareheaded. The sides are usually kept shorter and tapered, while the top remains long enough to sweep backward without sticking out.

Where it comes from

This look defined men’s grooming in the 1920s, a decade when hats were nearly universal. The need for hair to lie flat under headwear drove the trend. Hollywood actors such as Rudolph Valentino and Fred Astaire popularised the sleek aesthetic. By the 1930s, the style evolved into neater cuts with tapered napes, influencing modern fades. It remained a staple through the 1940s, associated with refined figures like Frank Sinatra, before giving way to longer, looser styles in the 1960s.

What it means

In the 1920s, a slicked head signified adherence to sanitary ideals and social respectability. Facial hair was largely abandoned as it was seen as hiding imperfections or suggesting poor hygiene. A well-oiled head showed one had the means to maintain a polished appearance. For older men, thinning hair combed back with light oil indicated wisdom rather than vanity. The style reflected a cultural shift towards cleanliness and modernity in the post-war era.

How it is made

Start with hair dampened by water, wiping away excess moisture. Apply an oil-based product like Brilliantine, petroleum jelly, or coconut oil directly to the scalp and strands. Use a comb to direct the hair straight back from the forehead over the crown. For a smoother finish without visible comb lines, use a soft brush for the final strokes. Part the hair in the centre, slightly off-centre, or deep on one side depending on face shape. Allow thick hair to dry slightly before applying product to avoid sogginess.

Who and what it suits

Straight hair is the easiest texture to manage for this style. Men with wavy hair can achieve the look using heavy oils or hot irons to straighten the strands. Curly hair may require significant product to suppress volume, though some wore it with only light smoothing. The style works best on those with sufficient density, as balding areas were often covered by hats or toupees. A deep side part can flatter rounder face shapes by adding structure.

Versions

Variations include the centre part, which was common in the early 1920s, and the deep side part, which helped men with thinning hair. The half-crown cut featured short, shaved sides with a few inches of length on top, hanging straight down. A short pompadour kept the top very short and combed up, resembling a military buzz cut. Some men with curly hair opted for a softer shape with loose waves brushed back rather than fully flattened.

In culture

The style is closely linked to the Jazz Age and films like The Great Gatsby. It represented the clean-cut ideal of the era, contrasting with the later rebellious looks of the 1950s and 1960s. The greasy nature of the products used led to household adaptations, such as lace doilies on chair backs to protect upholstery. Today, it is often revived in vintage-themed events or by subcultures appreciating early twentieth-century fashion.
