How many micro rings do I need?

A full head of micro ring extensions typically needs 100-200 strands with corresponding rings. Always order 10-15% extra rings as spares — some will be dropped or misshapen during fitting. Small rings for fine hair require more strands (up to 200), while large rings on thick hair may need fewer (around 120).

Do micro ring extensions damage hair?

Micro ring extensions are one of the least damaging methods when fitted correctly, as they use no heat or glue. The small aluminium or copper ring is simply clamped around the natural hair and extension strand. Damage only occurs from over-tightening, using rings that are too small, or neglecting maintenance.

How long do micro ring extensions last?

Micro ring extensions need maintenance every 6-10 weeks as the hair grows down from the scalp. During maintenance, the rings are opened, moved up closer to the scalp, and reclamped. The extension hair itself can last 6-12 months with good care. Total wearing time between maintenance is typically 8-10 weeks.

What ring size should I use?

Standard rings (5mm) suit most hair types. Small rings (3mm) are better for fine hair or areas where discretion is important (around the face). Large rings (5.5mm+) are for thick or coarse hair. The ring must fit comfortably around both the natural hair section and the extension strand without being too tight.

How We Calculate This

This calculator estimates the number of extension strands and micro rings needed based on coverage, hair density and ring size.

The formula

Strands = Coverage base x Density factor x Ring size factor

Rings = Strands + 10% spares

Fitting time = (Strands x 2.5 mins) + 20 mins prep
