CharacterAdded Doesn't Always Work Why Not? Does It Matter If Client Or Server Script?

Why doesn't character added work when the character is fully added? i dont get this, and its really messing up my custom character datastore save between games.

I found a fix, was to wait five seconds, then change character values. But if i dont have that, it sometimes doesn't work at all and ignores my other code in it.

Here is my code.

local PlrsFolders = game.ReplicatedStorage:WaitForChild("Profiles")
local selectface = game.ReplicatedStorage.Database.Items.Faces
local newhairboy = game.ReplicatedStorage.Database.Items.Hair.Hair.Boys
local newhairgirl = game.ReplicatedStorage.Database.Items.Hair.Hair.Girls

game:GetService("Players").PlayerAdded:connect(function(p)
p.CharacterAdded:connect(function(char)
wait(5)
if PlrsFolders[p.UserId].Char_Info.Bodyclr.Value == 1 then
char["Body Colors"].TorsoColor = BrickColor.new("Pastel brown")
char["Body Colors"].HeadColor = BrickColor.new("Pastel brown")
char["Body Colors"].RightArmColor = BrickColor.new("Pastel brown")
char["Body Colors"].LeftArmColor = BrickColor.new("Pastel brown")
char["Body Colors"].RightLegColor = BrickColor.new("Pastel brown")
char["Body Colors"].LeftLegColor = BrickColor.new("Pastel brown")
end
  end)
end)

It changes body color for different "Bodyclr" values.

Why does this work, but if i remove wait(5)

it wont?

How can i make sure the character loads in, what if it takes more than five seconds? and it doesn't load at all? what do i do to make it accurate?

Thank you.
