How to Prep New Bundles Before Coloring, Cutting, or Installation
New bundles don’t usually need a full salon-style rescue, but they do need a quick check before color, scissors, or a client’s head. In our warehouse, most avoidable issues start with one skipped step: someone installs or colors hair before inspecting, cleansing, or letting it settle. Here’s how we’d suggest you prep new bundles without wasting product or ruining good hair.
Open everything before you commit
First, lay all bundles on a clean towel and compare them in natural light. Check length, texture, color, bundle weight, and weft condition before you wash, color, or alter anything. A standard bundle is often around 95–100 grams, and longer lengths can look thinner even when the weight is correct. If anything looks off, take photos with the tags and packaging still visible, then contact your supplier before chemicals touch the hair. Once you color or cut it, most vendors can’t resell it, and that refund gets awkward fast.
Give the hair a light pre-color wash
Even clean-looking hair can carry factory dust, packing residue, or light styling products from handling. If you’re coloring, shampoo the bundles gently with a clarifying shampoo, rinse well, and let them air dry almost completely before mixing your formula. Don’t deep condition right before a color service, because heavy conditioners and silicone coatings can block even lift. For natural bulk hair for braiding that you’re only installing, a light wash is optional; just make sure the hair is fully dry before storing or braiding. If you’re working with weft hair extensions, support the weft while washing so you don’t tug tracks loose.
Do a strand test before the whole batch
I know, strand tests feel slow when the client is sitting right there. Do it anyway, especially if you’re lifting dark hair to blonde, trying a fashion shade, or mixing textures from different production lots. Take a small underneath section, time the process exactly, and let it dry before you judge the shade because wet hair always looks darker. Human hair can color beautifully, but previous processing matters more than the label does. If you regularly stock color-friendly hair, our starter bulk hair inventory guide can help you choose lengths and textures that sell without overbuying.
Prep wefts, tips, and tape tabs the right way
Before cutting, decide whether the weft is actually made to be cut anywhere, or whether you need to seal or reinforce cut ends. Some machine wefts fray badly if you snip them without planning, and hand-tied tracks usually need even more care. Keep your cuts clean, don’t shred the top band, and lay pieces in client-ready order instead of leaving a tangled pile on the counter. For tape in hair, avoid conditioner, oil, or shine spray near the tabs, or the bonds won’t hold like they should. A few minutes organizing now saves you from hunting through three wet bundles mid-install.
A simple pre-install checklist
- Inspect every bundle in daylight before washing or coloring.
- Measure lengths while the hair is straight, since curly hair pulls longer.
- Remove loose hairs from the top band and check for shedding.
- Clarify only when color or product buildup makes it necessary.
- Let hair dry fully before boxing, cutting, or applying most colors.
- Keep bundles matched by texture and lot, especially for 24-inch and longer styles.
- Store prepped pieces flat or hanging neatly until the appointment.
If you need a place to keep backup hair before the client arrives, use the same clean, dry routine we outline in our storage guide for bundles and wefts. Don’t leave freshly washed hair bunched up in a plastic bag overnight. Mildew smell is hard to fix and completely avoidable.
Do I have to wash new bundles before installing?
Not always. If the hair is going in as-is, it smells normal, and there’s no visible styling product, many stylists install straight from a clean package. Wash first if you’re coloring the hair, the client is sensitive, or the bundles feel coated or dusty.
Can I color every type of extension the same way?
No, and that’s where a lot of mistakes happen. Bulk hair, wefts, tape-ins, and pre-bonded tips have different parts that must stay free of color, conditioner, or oil, so protect tabs, bonds, and weft edges while you work. Test one small section first, keep notes on timing, and don’t assume two dark-brown bundles will lift identically.
Take the extra fifteen minutes to inspect, test, and organize before you change a single bundle. Your color result will be cleaner, your install will move faster, and you’ll have far fewer supplier conversations that start with “I already cut it.”
