A slick back haircut has remained one of the most iconic men’s hairstyles for decades. Its clean appearance, timeless appeal, and versatility make it a favorite among men of all ages. If you have a diamond-shaped face, a slick back can be especially flattering when it’s tailored to your facial proportions.
Diamond faces are known for prominent cheekbones, a narrower forehead, and a narrower jawline. The goal when choosing a hairstyle isn’t to hide these features but to create balance by adding fullness where needed while avoiding styles that make the face appear overly angular.
The good news is that many slick back variations do exactly that.
Why Slick Back Haircuts Suit Diamond Faces
A well-balanced slick back creates smooth lines that complement the distinctive shape of a diamond face.
Rather than emphasizing the cheekbones alone, it helps distribute visual attention across the forehead, crown, and jawline.
Benefits include:
- Creates a balanced silhouette
- Adds controlled volume on top
- Works with most hair types
- Pairs well with facial hair
- Suitable for professional and casual settings
The key is choosing a version with moderate volume and avoiding extremely tight sides if they make the cheekbones appear wider.
How to Tell If You Have a Diamond Face
You likely have a diamond face if these features match your own:
- Prominent cheekbones
- Narrow forehead
- Narrow chin
- Angular facial structure
- Face is longer than it is wide
Diamond faces are less common than oval or square shapes, but they pair exceptionally well with many modern men’s hairstyles.
Best Slick Back Haircuts for Diamond Faces
Classic Slick Back
The traditional slick back remains one of the most flattering options for diamond faces.
It creates balanced volume while maintaining clean, timeless styling.
Best for:
- Straight hair
- Medium-length hair
- Professional environments
- Classic grooming
Its moderate shape prevents the hairstyle from overpowering naturally defined facial features.
Slick Back with Low Taper
A low taper helps preserve some fullness around the lower sides of the head.
This creates better balance between the forehead, cheekbones, and jawline.
Benefits include:
- Soft transitions
- Conservative appearance
- Easy maintenance
- Balanced proportions
It’s one of the safest choices if you’re trying a slick back for the first time.
Slick Back with Mid Fade
A mid fade offers a modern appearance while maintaining enough side fullness to complement a diamond-shaped face.
This variation works particularly well for:
- Thick hair
- Straight hair
- Wavy hair
- Everyday styling
The fade creates clean lines without becoming overly aggressive.
Textured Slick Back
Texture adds natural movement that softens angular facial features.
Rather than creating a perfectly polished finish, it embraces a more relaxed appearance.
Ideal for:
- Thick hair
- Wavy hair
- Medium-length styles
- Casual looks
Use matte clay or styling paste for the most natural finish.
Slick Back Undercut
The slick back undercut creates strong contrast between the longer top and shorter sides.
When worn with moderate volume, it can look incredibly stylish on diamond face shapes.
It’s especially suited for:
- Thick hair
- Fashion-forward styles
- Men who enjoy daily styling
Avoid taking the sides too high if your cheekbones are especially prominent.
Long Slick Back
Longer slick back hairstyles create graceful movement and soften angular features.
The added length helps create a more balanced overall profile.
This style is ideal for:
- Medium to thick hair
- Longer hairstyles
- Men who enjoy versatile styling options
Regular conditioning keeps longer hair healthy and manageable.
Slick Back Pompadour
A pompadour-inspired slick back adds controlled lift to the front without overwhelming facial proportions.
Benefits include:
- Stylish profile
- Balanced height
- Modern appearance
- Strong visual texture
Aim for moderate height rather than an oversized pompadour.
Side-Part Slick Back
Adding a side part introduces asymmetry that naturally softens angular facial features.
It’s a refined option that’s perfect for:
- Business professionals
- Formal events
- Everyday office wear
- Weddings
This variation remains timeless while offering subtle visual interest.
Slick Back with Beard
Facial hair can help create additional balance by adding fullness around the jaw.
Popular beard styles include:
- Heavy stubble
- Short boxed beard
- Medium beard
- Tapered beard
Avoid overly long or bulky beards unless they suit your overall style.
Modern Slick Back Fade
Modern barbering techniques combine textured styling with clean fades to create a fresh take on the classic slick back.
Features often include:
- Natural texture
- Moderate height
- Clean fade
- Sharp neckline
- Soft transitions
It’s one of today’s most requested haircut styles.
Best Hair Types for Slick Back Hairstyles
Straight Hair
Straight hair naturally combs backward and produces the clean finish associated with traditional slick back hairstyles.
Thick Hair
Thicker hair creates excellent volume and allows for a variety of slick back styles.
Your barber can remove excess weight if needed.
Wavy Hair
Natural waves create movement that gives slick back hairstyles a softer, more modern appearance.
Styling cream works especially well for enhancing texture.
Fine Hair
Fine hair can still achieve a slick back with the help of volumizing products and proper blow-drying.
Lightweight styling products usually perform best.
What to Ask Your Barber
A clear consultation leads to better results.
Try saying:
“I’d like a slick back that complements my diamond face. Keep some fullness around the sides, leave enough length on top for natural volume, and avoid making the fade too high.”
Your barber can customize the fade based on your hair density and facial structure.
How to Style a Slick Back
Creating the hairstyle is simple.
Follow these steps:
- Start with towel-dried hair.
- Apply a small amount of styling product.
- Blow-dry backward while lifting gently at the roots.
- Shape the hair with a comb or brush.
- Finish with light hairspray if desired.
Natural movement usually looks better than forcing the hair perfectly flat.
