The Ra.One actor took to Twitter to praise his personal hairdresser.
"My messy hair has a life cos of my lovely and spiritual Dilshad (sic)," Khan posted, before directing fans to her salon.
Pastakia has known the star for ten years, after the stylist was introduced to him by wife Gauri Khan.
The actor cut his shoulder-length hair short in March as soon as filming had wrapped on Farhan Akhtar's Don 2.
"I insisted on getting my hair chopped off the same night the film's shooting was over," said Khan at the time.
The star was earlier forced to abbreviate the title of Billu Barber to Billu following caste related complaints from barbers groups in India.
Khan left Kolkatta on Thursday bound for Hong Kong and then Germany.
