Micro vs Standard vs Nano Keratin Extensions — Which Is Right for You?

All three use keratin capsules fused to your natural hair. The difference is capsule size, price, and which hair type each suits best. At WOW HAIR MIAMI in North Miami, we offer all three — so we can match the perfect method to your specific hair.

Price: $2 per capsule (all-inclusive)

Capsule size: 0.3-0.4g per strand

Best for: Fine, thin, or sensitive hair

Longevity: 3-4 months before rebonding

The Micro capsule is roughly half the size of Standard. It creates minimal tension on each natural strand — making it the safest and most comfortable option for clients with fine or color-treated hair.

Price: $3 per capsule (all-inclusive)

Capsule size: 1g per strand

Best for: Normal to thick hair, all types

Longevity: 3-4 months before rebonding

Standard Keratin Fusion is the most widely used professional method in the USA. Strong, durable bonds that lie completely flat. Works beautifully for most hair types and provides excellent value.

Price: $4 per capsule (all-inclusive)

Capsule size: Smaller than Micro

Best for: Very fine, short, or thin hair

Longevity: 2-3 months before rebonding

Nano bonds are virtually invisible at the root — undetectable even in updos and ponytails. The premium price reflects the additional time and precision required. For clients who tried other methods and found them visible, Nano is often life-changing.

Regardless of which method you choose, at WOW HAIR MIAMI we use exclusively 100% Slavic Remy Hair — sourced from Eastern Europe in 50+ shades. The hair quality is the same across all three methods.
