Before you commit to a new hair color or chemical treatment it is vital to understand how your hair will react. This is where a pre-treatment test comes in. A strand test is a simple way to determine your hair’s current state and anticipate its behavior under harsh formulas.

To begin, select a tiny lock from a hidden area like the nape of your neck or behind your ear. Use precision-cutting tools to cut a strand that is similar in diameter to a standard pen. Make sure the strand includes the root and at least two inches of length. Wash and dry the strand thoroughly so there is any trace of styling product that could skew your results.

Next, prepare a diluted portion of your chosen treatment according to the label specifications. Dab the solution onto the hair strand using a brush, being keeping it isolated from your roots. Leave the product on for the time specified by the manufacturer, but monitor it constantly. Check the strand every few minutes to see how it is responding in hue, structure, and stretch.

When the time is up, rinse the product off gently with cool water and pat dry with a towel. Compare the treated strand to the untreated hair vendors in china nearby. Look for signs of damage such as dryness, brittleness, or breakage. If the strand feels brittle and dry or fragments under tension, your hair may be too weakened for this process.

Also note any unexpected color results. If the strand shows unwanted warmth when you expected a cooler tone, you may benefit from a purple shampoo or gloss. If the strand appears intact with accurate pigment, you are likely safe to proceed. However, if the strand displays excessive breakage, it is best to consult a professional or choose a gentler option.

This simple test lasts under 10 minutes but can save you from costly mistakes. Conduct a strand test before each new application because your hair’s condition can change with the seasons.
