#2 – Darkest Brown
Best Fitzpatrick Types: III, IV, V, VI（neutral undertone）
How to brown extension match skin type with #2:
If you are Type III-VI with a neutral undertone, #2 provides deep, natural-looking darkness without being harsh. It blends seamlessly with nearly black natural hair.
Who should choose #2
- Type III neutral / olive
- Type IV neutral
- Type V neutral
- Type VI（as a slightly lighter alternative to black）
Who should avoid #2: Type I and II（too dark → harsh contrast）
#3 – Cool Brown
Best Fitzpatrick Types: I, II（cool）, III（cool）
How to brown extension match skin type with #3:
Cool undertones need ash-based browns. #3 neutralizes facial redness and makes blue or grey eyes pop. This is the brown extension match skin type solution for clients who have tried warm browns in the past and ended up with orange or brassy results.
Who should choose #3
- Type I cool（porcelain skin, blue eyes）
- Type II cool（fair skin that burns easily）
- Type III cool（rare but exists）
Who should avoid #3: Warm or olive undertones（#3 will look dull and grey）
#4 – Dark Brown
Best Fitzpatrick Types: II（neutral）, III, IV, V（neutral）
How to brown extension match skin type with #4
True neutral brown is the safest option. It has no red and no ash, making it the most versatile shade for brown extension match skin type when you are unsure between warm and cool.
Who should choose #4
- Type II neutral
- Type III（any undertone—this is the universal bridge）
- Type IV olive or neutral
- Type V neutral
Who should avoid #4: Type I（too dark）, Type VI（not dark enough）
#8 – Light Brown
Best Fitzpatrick Types: II（warm）, III（warm）, some IV
How to brown extension match skin type with #8

Who should choose #8
- Type II warm（fair but golden）
- Type III warm（golden or honey skin）
- Type IV warm（seeking lighter dimension）
Who should avoid #8: Type I, Type V, Type VI（too light → low contrast, washes out deeper skin）
#1C – Mocha Brown
Best Fitzpatrick Types: III（warm）, IV（warm）, V（warm）
How to brown extension match skin type with #1C
Mocha has beige-warmth without orange tones. It creates sunlit dimension on warm golden skin. For clients with hazel eyes that have gold flecks, this is the brown extension match skin type that makes their eye color stand out.

- Type III warm（golden beige skin）
- Type IV warm（tanned golden skin）
- Type V warm（caramel skin）
Who should avoid #1C: Type I, II cool, and olive undertones（#1C will pull too yellow/orange）
#2A – Espresso Brown
Best Fitzpatrick Types: I, III（olive）, IV（olive）, V（olive）
How to brown extension match skin type with #2A
Olive skin（green-gray undertones）fights with warm browns. #2A provides a cool, dark ash base that cleans up the complexion. This is the brown extension match skin type choice for Mediterranean, Latinx, and Middle Eastern clients with olive skin who find warm chocolates look muddy.
Who should choose #2A
- Type I（dramatic high-contrast look）
- Type III olive（greenish-beige skin）
- Type IV olive（Mediterranean / Latinx olive）
- Type V olive（green-brown skin）
Who should avoid #2A: Warm undertones（#2A will look flat and ashy）

Who should choose #2B
- Type IV warm（deep tan, golden skin）
- Type V warm（caramel to mahogany）
- Type VI（deep brown to black skin）
Who should avoid #2B: Cool or olive undertones（#2B will pull too red/orange）
