How I sped up my hair growth with rosemary oil ~ it has grown approx 7cm in around 4 months and feels more voluminous, too! I did this once a week the night before washing my hair. I’m using the Mielle rosemary mint scalp & hair strengthening oil, I’ve linked the exact one in my ‘Rosemary 🌿’ highlight. This isn’t an ad, I bought the oil myself after seeing so many rave about it on social media. What other growth remedy should I try next? Keen to hear what has worked for you!
