Flatness is everything. Honestly, if you’re spending three hours in a chair and $200 on bundles just to end up with a "hump" near your temple, something went wrong before the needle even touched the thread. The foundation is the side part sew in braid pattern. Get that wrong, and you're fighting gravity the whole month. It’s the difference between hair that looks like it’s growing out of your scalp and hair that looks like a hat sitting on top of your head.
Most people think you just braid everything back and leave a little bit out. That is a recipe for disaster.
The "Curvature" Secret for a Natural Side Part
When you’re mapping out a side part sew in braid pattern, the most common mistake is braiding in straight lines. Straights lines are for middle parts. For a side part, you need a curved foundation that mimics the way hair naturally falls over the parietal ridge of your skull.
The "C-Shape" technique is what the pros use. Instead of braiding from front to back in a grid, you want to create a focal point where your part will actually sit. You start the braid right at the edge of your leave-out and curve it around the head. This creates a literal ledge for the weft to sit on so it lays flush. If you don't do this, the tracks will have to "climb" over the braids, which creates that bulky, unnatural height we all hate.
Think about it this way. Your head isn't a square. It’s a sphere. If you put straight tracks on a round surface, they’re going to buckle. You’ve probably seen those installs where the side part looks like a cliff. That's usually because the braids were too thick or the direction didn't account for the "swing" of the hair.
Why Perimeter Braids Are Your Insurance Policy
You need a sturdy anchor. If the perimeter braid—the one that goes around your hairline—is too loose or too thin, the weight of the sew-in will pull on your edges. That’s how you end up with traction alopecia.

I’ve seen stylists try to be "gentle" by making the perimeter braids big. Don't do that. Big braids are bulky. You want small, firm (but not tight) beehive-style transitions at the edges. This allows the tracks to be sewn closely together without creating a gap.
Some stylists prefer the "v-motion" or "diagonal" pattern. This works incredibly well for deep side parts. Basically, the braids on the "heavy" side of the part (the side with more hair) should be angled diagonally toward the back of the neck. On the "thin" side, they can be more vertical. This asymmetry is intentional. It balances the weight of the extra bundles you’re likely putting on the heavy side.
The Leave-Out Trap
Let’s talk about leave-out. People get greedy. They want a deep side part but only leave out a sliver of hair. Unless you have the density of a lion’s mane, that sliver isn't going to cover the tracks when the wind blows.
You need enough hair to cover the first two tracks completely. This means your side part sew in braid pattern needs to leave a "U" or "L" shaped section of natural hair that is at least an inch wide. If your hair is fine, make it an inch and a half.
The braids immediately adjacent to the leave-out must be the thinnest braids on your entire head. We call these the "anchor braids." If these are chunky, your leave-out will have to jump over a hurdle to meet the weave. It creates a visible line of demarcation that screams "I have an install."

Common Patterns and When to Use Them
- The Classic Beehive: Great for longevity. It’s one continuous braid that circles the head. For a side part, you just shift the "center" of the beehive to the side. It’s solid, but it can be hard to dry after a wash.
- The Frontal Cross-Over: This is where the braids in the front go horizontally across the forehead area and then transition into vertical braids in the back. This is the king of flatness.
- The Zig-Zag: Honestly, this is mostly for people with very thick natural hair who need to de-bulk the foundation. It spreads the mass of the hair out so the scalp stays relatively level.
Handling the "Bulk" at the Nape
The back of the head is where side parts go to die. Or rather, where they go to get "puffy."
Often, stylists finish the braids and just sew the ends together in a big lump at the nape of the neck. When you put your tracks over that, it looks like you’re hiding a snack back there. The pro move is to sew those braid tails down flat against the other braids using a crochet hook or needle and thread before you even start with the bundles.
Everything must be flat. If you feel a bump with your hand, you will see a bump with your eyes.
Real Talk: The Tension Issue
We need to address the "tightness" myth. There is a specific segment of the hair community that believes if it doesn't hurt, it won't last. That is categorically false.
A side part sew in braid pattern should feel secure, not like a facelift. If your skin is pulling at the temples, the braids are too tight. This doesn't just damage your hair; it actually makes the install look worse. Inflammation causes the braids to lift away from the scalp, which creates—you guessed it—more bulk.

Use a net. Seriously. A weaving net is the "cheat code" for a side part. It allows you to sew the tracks exactly where they need to be, regardless of where the braids are. If your braid pattern has a gap because of your head shape, the net bridges that gap. It also takes the tension off your natural hair and puts it on the net itself.
Maintenance and the "Shift"
Over four to six weeks, your hair grows. Your side part sew in braid pattern will shift. The flat look you had on day one will start to rise.
This is why the initial pattern matters so much. A curved pattern holds its shape better as it grows out compared to a straight back pattern. When straight back braids grow out, the tracks start to flop over. A curved anchor braid keeps the track directed toward the face even when there’s a half-inch of new growth.
Actionable Steps for Your Next Appointment
To ensure you get the flattest, most natural side part possible, follow these specific steps during your prep and install:
- Blow dry your hair straight: Braiding on "blown out" hair results in much flatter, more consistent braids than braiding on damp or curly hair.
- Request the "Anchor Braid" method: Ask your stylist to make the braids surrounding your leave-out half the size of the braids in the back.
- Map the part first: Before a single braid is started, have the stylist use a rat-tail comb to precisely part your leave-out. This ensures the braid pattern is symmetrical to your actual desired look.
- Use a weaving net: If you plan on keeping the install in for more than a month, the net is non-negotiable for maintaining the integrity of the braid pattern.
- Check for "The Lump": Before the hair is sewn in, run your hand over the braids. If you feel any thick spots, ask the stylist to unbraid and redistribute the hair or sew the braid tails flatter.
- Minimize "Bulk" at the Crown: Ensure the braids at the top of the head are directed away from the part to allow the wefts to lay as close to the scalp as possible.
The foundation is 90% of the work. If you nail the side part sew in braid pattern, the rest is just sewing. Focus on the curve, respect the leave-out, and always, always flatten those ends at the nape. Your edges—and your mirror—will thank you.
