Longest Hair In Naruto??

[TonyJT]

Oddly enough, that title might belong to a man.

[Lrrrrr]

Jiraiya I believe.

[UchihaMadara01]

Madara.

[xXBlazinNinXx]

J man

[celarian]

jaraiya uses ninjutsu to lengthen his hair,

[bladesofchaos360]

Jiraiya and fourth mizukage.

[UchihaMadara01]

jaraiya uses ninjutsu to lengthen his hair,

Exactly!.

[-6 Paths-]

I believe Jiraiya is the one worthy of that title :y

[SasoriOfTheRedSaand]

It's Mei.

[Uchiha Kisuke]

Madara

[Kages]

Jiraiya and in a filler Kurenai as well.

[Sonnelion]

J-man
R.I.P.

[Sage of Nature Creation]

Jiraya has the longest hair.

[Konan is a Badass]

Mizukage

Jiraiya if you include that technique though its not the actual lenght

[~MC117~]

Jiraiya and mei.

[Kyubi Mode]

Jiraya, ofcourse

[laharl81]

Longest would probably be madara if you don't Jiraiyas technique, If not longest its atleast the thickest, I feel like even a chainsaw can't cut that.

[phoenixforcexD]

mei and jiraya
but jiraya can make it expand so i guess him

[UchihaInza]

jiraiya or itachi

[UchihaInza]

or even madara

[hanabeelee]

for me, i think it's Kushina Uzumaki or Mei Terumi
