Cutting seconds off your lap time requires more than just technique and endurance. Hydrodynamics play a massive role in how efficiently you move through the water during a workout.
Hair is a major source of resistance in the pool. Loose strands act like tiny anchors, creating turbulent flow and slowing your forward momentum significantly.
Choosing the right hairstyle minimizes surface area and prevents water from trapping against your head. This ensures every stroke translates into maximum distance without unnecessary friction.
A secure, flat hairstyle also helps your swim cap stay in place. This prevents the cap from sliding up and creating a “bubble” of water that increases drag.
Whether you are training for a competition or swimming for fitness, your hair shouldn’t hold you back. These styles prioritize stability, compression, and a streamlined profile.
1. Tight Low Nape Bun
The tight low nape bun is a staple for serious lap swimmers who want to keep their profile as flat as possible. By positioning the bulk of the hair at the curve of the neck, you allow the swim cap to sit flush against the skull.
This style is particularly effective because it prevents the “bump” at the top of the head which can disrupt water flow. It stays secure even during aggressive flip turns and high-speed intervals.
To achieve the best results, use a snag-free elastic and smooth the hair down with a bit of leave-in conditioner. This reduces flyaways that might escape the cap and create micro-drag.
2. Classic French Braid
A classic French braid is excellent for keeping every layer of hair locked into place. Because it starts at the forehead and incorporates hair as it moves down, it prevents loose strands from shifting.
This hairstyle creates a very thin, uniform texture along the back of the head. When tucked under a cap, it compresses easily, ensuring the cap maintains a smooth, rounded shape for better hydrodynamics.

3. Double Dutch Braids
Double Dutch braids, also known as boxer braids, offer superior security by dividing the hair into two distinct, tight rows. This distribution of hair prevents a single large lump from forming under the swim cap.
By keeping the hair close to the scalp, you achieve a more symmetrical profile in the water. This symmetry is vital for maintaining balance and reducing side-to-side resistance during the freestyle stroke.
This style is highly recommended for those with very thick or long hair. It compresses the volume effectively, making it much easier to fit everything inside a standard silicone racing cap.
4. The Bubble Ponytail
The bubble ponytail is a modern solution for swimmers who prefer not to braid but need total control. By placing elastics every two inches down the length of the tail, you prevent the hair from billowing.
In the water, a standard ponytail acts like a rudder, creating significant drag behind the head. The “bubbles” keep the hair contained in a singular, narrow line that follows the body’s path.
This style works best when the ponytail is positioned low. It provides a streamlined exit for water moving over the head, ensuring that the hair does not whip around during butterfly or breaststroke.
5. High Ballet Bun
For swimmers who prefer a cap-free experience or use a high-volume cap, the high ballet bun is a top choice. Placing the bun at the crown of the head can help some swimmers maintain a better head position.
This style keeps the neck completely clear, which can feel more aerodynamic during certain strokes. It is essential to pin the bun flat against the head to ensure it doesn’t wobble while swimming.

6. Sectioned Low Ponytail
A sectioned low ponytail is a variation of the bubble tail that focuses on the base of the head. It starts with a small ponytail at the top, which is then fed into a second and third section.
This layering technique ensures that shorter layers near the face are pinned back securely. It eliminates the risk of “wispy” hairs escaping and creating drag around the goggles or ears.
The final result is a very flat, controlled trail of hair. It is an ideal setup for swimmers who find that single elastics often slide out during high-intensity sets or diving starts.
7. Crown Braid Halo
The crown braid, or halo braid, involves wrapping the hair around the circumference of the head. This distributes the weight and volume of the hair evenly, rather than concentrating it in one spot.
By creating a “flat” surface around the head, this style allows the swim cap to achieve its most aerodynamic shape. There are no protrusions to catch the water or cause the cap to tear.
This is a professional-grade solution for those with exceptionally long hair. It keeps the hair completely away from the neck and shoulders, providing total freedom of movement for the arms.
8. Tight Cornrows
Cornrows are perhaps the most aerodynamic hairstyle available for the pool. Because the hair is braided directly against the scalp in small sections, there is virtually zero bulk or movement.
This style allows water to flow over the scalp with almost the same efficiency as a bald head. It is the preferred choice for many elite athletes who require maximum speed and zero distractions.

9. Slicked-Back Single Braid
The slicked-back single braid combines the benefits of a sleek front with a controlled back. Using a small amount of water-resistant pomade or conditioner helps the hair stay plastered to the scalp.
The braid itself should be tight and thin to minimize its “tail” effect in the water. This style is excellent for maintaining a clear field of vision, as no hair can fall forward during turns.
For those who swim without a cap, this is one of the most stable options. It keeps the hair from tangling into a “birds nest” caused by the constant friction of the water.
10. Triple Low Buns
Triple low buns involve splitting the hair into three small sections at the nape of the neck. Each section is twisted into a tiny, flat knot and secured tightly against the skin.
This technique is superior to a single bun because it flattens the hair much more effectively. Smaller buns are less likely to shift or create a large pocket of air inside a swim cap.
This is a great “drag-reduction” hack for swimmers with very thick hair that usually stretches a cap to its limit. Spreading the volume across three points creates a smoother overall silhouette.
11. Twisted Rope Braid
The twisted rope braid is faster to execute than a standard braid but offers similar hydrodynamic benefits. It involves twisting two sections of hair around each other to create a dense, heavy cord.
Because the rope braid is more compact than a three-strand braid, it tends to stay submerged and “follow” the body more closely. This reduces the “whiplash” effect during fast rotation in freestyle.
Ensure the ends are secured with a heavy-duty elastic. This prevents the twist from unraveling, which would immediately increase drag and potentially tangle in the swimming goggles’ strap.

Flat twists are similar to cornrows but involve twisting two sections of hair instead of braiding three. This results in a style that lies extremely close to the scalp and feels very lightweight.
This hairstyle is excellent for reducing the frontal surface area of the head. When the water hits the forehead, it glides over the flat twists with minimal resistance, improving overall streamline.
Flat twists are also very easy to fit under a racing cap. They provide a textured surface that actually helps silicone caps “grip” the head, preventing them from sliding off during a race.
13. Low Fishtail Braid
A fishtail braid is much tighter and flatter than a traditional braid. The small, interlocking sections of hair create a very thin profile that cuts through the water with ease.
While it takes longer to style, the hydrodynamic payoff is significant for lap swimmers. The braid is less likely to “puff up” when wet, maintaining its streamlined shape throughout the workout.
This style is particularly effective for swimmers who experience a lot of “drag-pull” at the back of their head. The fishtail stays centered and steady, even during high-velocity dolphin kicks.
14. Inside-Out Ponytail
The inside-out ponytail, or topsy tail, involves pulling the ponytail through a gap above the elastic. This “tucks” the base of the hair closer to the scalp and flattens the transition.
By eliminating the protruding elastic bump, the water can flow more smoothly over the back of the head. It is a quick and effective way to “streamline” a basic ponytail for casual laps.
To maximize the effect, repeat the “flip” multiple times down the length of the hair. This creates a series of flat, interconnected links that stay close to the spine while swimming.

A vertical braided bun starts with a braid that is then coiled into a long, flat oval shape rather than a round ball. This shape mimics the natural curve of the back of the head.
By distributing the hair vertically, you avoid a concentrated point of resistance. This is highly effective for swimmers who spend a lot of time on their back doing backstroke laps.
The vertical orientation ensures that the bun does not interfere with the water’s path over the top of the head. It keeps the profile slim and minimizes the “wake” created by the swimmer’s head.
16. Crossed Dutch Braids
Crossed Dutch braids involve starting two braids at the temples and crossing them over each other at the back of the head. This creates an “X” pattern that locks the hair down.
This style provides maximum stability for the “sides” of the head, which are often overlooked. Keeping the sides flat is crucial for reducing drag during head rotation for breathing.
The crossing action helps to pull the hair even tighter against the skull. This results in a very rigid, aerodynamic structure that is perfect for sprinters looking to shave off milliseconds.
17. The “Pineapple” Bun
The pineapple bun is specifically designed for swimmers with highly textured or curly hair. By gathering the hair at the very top of the head, the curls are compressed without being crushed.
For those using a “bubble” cap or a specialized large-volume cap, this keeps the bulk out of the way of the neck and shoulders. It allows for a full range of motion during the recovery phase of the stroke.
This style ensures that the weight of the hair is centered over the body’s axis. This helps maintain a neutral head position, which is the foundation of efficient, low-drag swimming.

The best way to reduce drag without a cap is to use very tight braids, like cornrows or Dutch braids, and secure them with multiple elastics. Applying a small amount of biodegradable hair oil can also help the hair “slick” back and repel water.
Which hairstyle is best for competitive racing?
Double Dutch braids or tight cornrows are generally considered the best for racing because they lie flattest against the scalp. These styles allow a silicone racing cap to fit perfectly, creating the most aerodynamic “egg” shape possible for the head.
Will these hairstyles prevent chlorine damage?
While hairstyles themselves don’t block chlorine, tight styles like braids and buns reduce the surface area of hair exposed to the water. Combining a tight style with a pre-swim rinse of fresh water and a cap is the best defense against chemicals.
How tight should my hair be for lap swimming?
Your hair should be secure enough that it does not move during a flip turn, but not so tight that it causes a headache or “swim cap pressure.” Finding a balance is key; if the style feels stable when you shake your head, it will likely hold up in the pool.
Is it better to have a high or low bun for hydrodynamics?
A low bun at the nape of the neck is generally more aerodynamic as it fills the natural curve between the head and shoulders. However, some swimmers prefer a high bun to keep their neck completely clear; both are effective if they are pinned flat.
Should I braid my hair wet or dry before swimming?
Braiding hair while it is slightly damp with fresh water and a bit of conditioner is usually best for swimming. This makes the hair more pliable, allows for a tighter braid, and helps protect the hair shaft from absorbing chlorinated pool water.
