Why Hair Sticks Out of Capsules After Hair Extensions

Hair extensions can create beautiful length and volume, but many clients experience a common issue: short hairs sticking out of the keratin capsules. This problem can affect the overall look and feel of the extensions, making them appear messy or unnatural. In this article, we will explain why hair starts to poke out of the capsules, whether it is normal, and how to prevent it.

Yes — to some extent, it is completely normal. Capsule extensions are made of natural human hair, which means they behave just like your own strands. Over time, they may shift, lift, or loosen due to daily wear, making some hairs more visible.
However, if the problem becomes too noticeable, it may indicate improper installation, poor-quality materials, or lack of maintenance.

1. Natural Shedding of Your Own HairEvery human sheds 50–100 hairs daily. When your natural hair is bonded inside a keratin capsule, the shed strands cannot fall out — they remain inside the bond.
As the capsule grows out, the accumulated shed hair may twist, bend, or stick out.
2. Poor-Quality or Over-Processed Extension HairCheap or heavily processed hair tends to:

• break easily
• tangle
• lose elasticity
• dry out and puff up

This leads to short strands sticking out around the bonds.
3. Improper Installation TechniqueIf the stylist:

• takes too large or too small a section
• applies uneven heat
• uses too much or too little keratin
• attaches extensions too close to the scalp

then the bonds may sit incorrectly and cause visible outgrown hair.
4. Incorrect Capsule Shape or WeightIf the capsules are:

• too thick
• poorly rolled
• not sealed tightly

they may cause hairs to escape and stand out in different directions.
5. Natural RegrowthAs your roots grow, the capsules shift downward and the hair inside them loosens. New growth creates movement that can push small hairs outward.
6. Daily Mechanical FrictionHair often sticks out from capsules because of:

• sleeping without protective braids
• friction from clothing, scarves, coats
• brushing too aggressively
• frequent styling
• Over time, friction lifts the bonds and disturbs the hair inside.

7. Lack of Proper Aftercare
If you use the wrong products — especially those containing oils, silicones, or sulfates — they can:

• soften the keratin
• make capsules slip
• cause frizz around the bonds
• This encourages hair to pop out.
