It controls the waves though the rain is wild (7)

Ross

I believe the answer is:

hairnet

I'm a little stuck... Click here to teach me more about this clue!

'it controls the waves' is the definition.
The definition suggests a singular noun which matches the answer.

'the rain is wild' is the wordplay.
'is wild' indicates anagramming the letters.
'the'+'rain'='therain'
'therain' is an anagram of 'HAIRNET'.

'though' acts as a link.

Can you help me to learn more?

(Other definitions for hairnet that I've seen before include "It keeps locks in place" , "In heart (anag)" , "It protects locks" , "The rain (anag) - used after shampooing?" , "keeper of locks" .)
