Embracing a bold new look with a 90-degree haircut, also known as an undercut, can be an exciting transformation. This style, popularized by celebrities like Zayn Malik and Harry Styles, features short hair at the sides and back, contrasting with longer hair on top. Here's a comprehensive guide on how to achieve this look, from preparation to maintenance.
Understanding the 90-Degree Haircut
The 90-degree haircut, as the name suggests, is cut at a 90-degree angle, creating a sharp contrast between the short and long sections. The length on top can vary, from a few inches to several inches, depending on your preference. The key is the dramatic difference in length, which creates a striking, modern look.
Preparation: Gather Your Tools
Before you start, ensure you have the right tools. You'll need:

- Clippers with guard sizes (ideally, a #1 or #2 guard for the sides and back)
- A comb
- Scissors
- Hair thinning scissors (optional, for blending)
- Hair clips
- Hair cutting cape
- Hair cutting scissors
- Hair cutting comb
Step-by-Step: Creating the 90-Degree Haircut
Sectioning the Hair
Start by brushing your hair to remove any tangles. Then, using a comb and hair clips, section off the top part of your hair. This will be the longer section that you won't cut. The remaining hair will be the part you'll cut short.
Cutting the Sides and Back
Using your clippers with a #1 or #2 guard, start at the nape of your neck and work your way up to the temples. Be careful around the ears and hairline, using a smaller attachment or scissors for precision. Ensure you maintain a straight, 90-degree line as you cut.
Blending the Lengths (Optional)
For a more seamless transition, you can blend the lengths using hair thinning scissors. Start at the top of the short section and work your way up, gradually increasing the length as you go. This will create a more natural fade effect.

Cutting the Top Section
Unclip the top section of your hair. Decide on the desired length, then use scissors to cut this section to your preferred length. Ensure you're cutting evenly and maintaining the desired shape.
Styling and Maintenance
Once you've achieved your desired look, style the longer section as desired. For maintenance, you'll need to trim the sides and back every 4-6 weeks to keep the sharp contrast. You can also use hair products to style the longer section, such as pomade or wax.
Safety and Precautions
Always remember to be careful when using clippers and scissors. Work in a well-lit area and take your time. If you're unsure about any aspect of the cut, it's always best to consult a professional.

Embracing a 90-degree haircut can be a bold and exciting change. With the right tools and techniques, you can achieve this striking look at home. Happy cutting!
