Extensions are not an add-on at Addendum. They are part of our foundation.
For nearly two decades, we have specialized in extension work that is thoughtful, precise, and fully customized. We offer every major method, including K-Tips, hand-tied sewn wefts, tape-ins, and custom hybrid combinations. Not because more options sound good, but because real results require the right solution for each individual head of hair.

The Standard of Modern Beauty
When it comes to extensions,
There is no single system that works for everyone. The right extension plan depends on your hair, your lifestyle, your goals, and how you want your hair to feel day to day. Sometimes that means subtle density. Sometimes it means length. Sometimes it means using extensions to create dimension and brightness without pushing your natural hair too far. Often, it means combining methods to get the most natural and wearable result.
Customization is not a buzzword here. It is the entire point.
What truly sets Addendum apart is that we have our own extension line. This allows us to remove the usual friction from the process. No waiting for hair to be ordered. No second appointment just to install. Your consultation becomes the beginning of a complete plan, and everything is prepared for your service so the experience stays seamless and intentional from start to finish.
Because we control the hair we use, we also control the quality, the consistency, and the outcome. We do not oversell. We do not over-install. We only use what your hair actually needs. If your blend requires multiple tones, we build that into your design instead of asking you to buy more hair than necessary. The result is less waste, more precision, and hair that looks refined, natural, and considered.
Everything we do is designed around longevity, integrity, and how your hair will live in the real world.

Healthy hair is not optional. It is the standard.
At Addendum, extensions are not just about adding length or fullness. They are also a tool for preserving the health of your natural hair. We often use extensions strategically to create brightness, dimension, or contrast without over-bleaching or over-processing your own hair.
This approach allows us to create impactful, high-end results while keeping your natural hair stronger over time. The goal is not a dramatic change for one appointment. The goal is a long-term plan where your hair continues to look better, feel better, and stay healthy with each visit.
Hair Integrity and Color Strategy
Let's Talk Process,
Every extension experience at Addendum begins with a real conversation.
We look at your current hair, your history, your routine, and your long-term goals. From there, we design a plan that makes sense for your hair and your life. Sometimes that means one method. Sometimes it means a combination. There are no preset packages and no one-size-fits-all answers here.
Because we carry our own extension line in-house, your plan moves directly from concept to execution. Once your design is set, everything is prepared for your appointment so the process stays efficient, intentional, and stress-free.
The Consultation Experience
01
Longevity is part of the service.
At Addendum, maintenance is never just a quick move-up. When you come in for extension maintenance or a weft service, we fully remove the hair first. Your natural hair and scalp are thoroughly cleansed so everything starts fresh. Your extensions are washed, conditioned, and blow dried before they are reinstalled. This ensures that your hair goes back on your head in the best possible condition, every time.
Most salons simply move the hair up and reinstall it. Our approach is rooted in scalp health, hair integrity, and long-term results. We treat your extensions with the same level of care as your natural hair, because they are part of your hair story now.
This process protects your scalp, preserves your natural hair, and significantly extends the life of your extensions. Our goal is simple. Your hair should feel comfortable, look beautiful, and stay wearable long after you leave the salon.
We also guide you on home care, product choices, and maintenance timing so your hair continues to look effortless between appointments.
Care and Maintenance

This is not the industry standard, but it is ours.
Extension services at Addendum are fully customized, and pricing reflects the method, amount of hair, and level of detail your hair requires.
Most transformations begin around $1,500, with many clients investing around $2,500 for a complete, customized result. More extensive changes may be higher depending on your goals and your hair.
Your stylist will always walk you through your plan, your investment, and your maintenance schedule during your consultation so everything feels clear, aligned, and intentional.
Investment and Expectations
03
Extensions at Addendum are not about excess. They are about precision.
They are about hair that looks natural, feels effortless, and supports the health of your own hair over time. Every decision we make is rooted in experience, restraint, and a long-term view of your hair.
That is the Addendum standard.
