Choosing hair extensions online should not be based on guesswork. A shade that looks like classic blonde or brown on a screen can have a cool, neutral, or warm undertone. What also matters is the area to which the strands are being matched: not the roots, but the lengths and ends of your natural hair.
In this guide, we show you how to identify your undertone, prepare a reliable photo, and use two forms of ARIA HAIR support: ARIA Selection, which narrows down your choices to available products in 60 seconds, and ARIA Concierge, where an expert confirms the shade based on your photos.
Why is natural hair color not uniform?
Natural hair almost always combines several tones. The roots may be darker, the lengths more neutral, and the ends lighter and warmer. The appearance of the color is influenced by natural pigmentation, previous coloring, the sun, and the way the hair reflects light.
This is why well-matched strands do not need to be identical in every hair. A multi-tonal shade can blend more naturally with the highlights present in your hairstyle. With balayage, sombre, or significant color variation, combining two shades is often the right solution.
Cool, neutral, or warm? Identify your undertone
Cool undertone
Ash, pearly, silvery, or platinum highlights dominate. The hair does not have obvious gold, honey, or copper tones.
Neutral undertone
This is a balance between cool and warm highlights. The color can have a beige, coffee, or classic character and does not change drastically depending on the light.
Warm undertone
Golden, honey, caramel, copper, or strawberry highlights are visible. These are easiest to spot in natural daylight.
Tip: assess the color by a window, without direct sunlight. Warm bathroom lighting and automatic phone filters can alter the shade's temperature.
Which part of the hair should extensions be matched to?
The most common mistake is matching strands to the roots. Hair extensions blend with your hairstyle primarily from the ear down, so the reference point should be the mid-lengths and ends.
If your roots are a dark blonde and the lengths are lightened to a light beige, strands matched solely to the roots may create a darker line at the bottom of your hairstyle. The correct shade should seamlessly continue the color visible on the lengths.

ARIA Concierge: personal shade confirmation
If your hair has a balayage, several distinct tones, non-standard coloring, or you want to confirm your ARIA Selection result before purchasing, use ARIA Concierge. An expert analyzes your current photos and helps assess the shade and potential color combinations.
ARIA Selection provides an immediate product recommendation. ARIA Concierge is the next step: a personal confirmation for situations where the color requires an expert eye.
How to take a photo for a color consultation?
- Light: choose diffused daylight by a window. Avoid harsh sun.
- Background: stand in front of a light, neutral wall.
- Hair: should be dry, loose, and thoroughly brushed.
- Frame: show the back of your head and the full length down to the ends. An additional side photo will make it easier to assess highlights.
- Phone: turn off the flash, portrait mode, filters, and color correction.
Do not take the photo under yellow incandescent light, in dim light, or with a flash. Such conditions can make cool blonde look warm and neutral brown look copper.
What about balayage or non-standard colors?
With multi-tonal coloring, an expert may suggest combining two shades in appropriate proportions. This allows you to recreate lighter highlights, natural roots, or the transition visible on the lengths.
If the right solution is not in the regular collection, ARIA Atelier allows for a custom Tape-In or Keratin Bonds order. The specification can include a non-standard shade, length, and weight, and the details are confirmed before production.
Most common mistakes when choosing color online
- matching strands only to the roots,
- assessing color in artificial, warm lighting,
- relying on the shade name instead of its temperature,
- sending a photo with a filter or flash,
- ignoring the difference between the color of the lengths and the ends.
How to start the selection?
First, use ARIA Selection to get a recommendation for method, shade, length, and volume in 60 seconds. If you need confirmation or have complex coloring, prepare photos according to this guide and send them to ARIA Concierge via WhatsApp.
A precise selection starts with the right light and undertone assessment. It ends with a recommendation that takes into account the actual color, structure, and the effect you want to achieve.
