PLUCHARM / PROFESSIONAL BUYING GUIDE
Human hair extensions may already be chemically processed. Do not assume they can tolerate bleaching, repeated colouring or every toner. Ask for product-specific guidance and have a professional assess a small strand before treating a full set.
| Before a chemical service | Confirm |
|---|---|
| Product | Exact method, grade, shade and order reference |
| History | Known lightening, colouring or texture processing |
| Assessment | Professional strand test and condition review |
| Terms | Any supplier restrictions on altered products |
Check the processing history first
Tell the supplier the exact shade and product reference. Ask whether lightening, colouring or texture processing has already occurred and what further services are permitted. A human hair or Remy label does not establish chemical compatibility.
Distinguish depositing colour from lightening
A darker target, a grey tone and a lighter blonde require different assessments. Porosity and the existing colour can affect uptake and uniformity. This guide does not prescribe a developer strength, bleach formula or processing time; those decisions require the product instructions and a qualified colourist.
There is no safe universal number of dye sessions
The number of previous services alone cannot establish remaining tolerance. Condition, processing history, strand-test results and the proposed formula matter. Repeated treatment can alter texture, colour and strength even if an earlier service appeared successful.
Order the closest suitable shade when possible
For a salon or private-label range, approving the desired colour before production can reduce the need for later correction. Keep a record of any treatment applied to your sample and ask how alterations affect the agreed returns or warranty conditions.
