Womanizer has short length, wavy hair, too (8)
I believe the answer is:
lothario
'womanizer' is the definition.
(I know that Lothario is a type of womanizer)
'short length wavy hair too' is the wordplay.
'short length' becomes 'l' (abbreviation in geometry; 'short' asks for an abbreviation).
'wavy' is an anagram indicator (letters wave around).
'hair'+'too'='hairtoo'
'hairtoo' is an anagram of 'othario'.
'l'+'othario'='LOTHARIO'
'has' is the link.
(Other definitions for lothario that I've seen before include "Successful womaniser" , "Womaniser, philanderer" , "A Gay libertine" , "Heartbreaker" , "Casanova" .)
