Hair Growth Products

For background, I have always had very thin hair and keeping it long was getting annoying so I cut it and have been keeping it pixie cut short for the last 5ish years.

I’ve noticed that it looks and feels a lot healthier since I stopped dying it (surprise surprise lol) and I’ve decided to grow it out again. The only thing is that it grows SO slow. I last got it cut back in September 2025 and it’s grown maybe an inch and a half since then. I’d like it to be down to my shoulders for an event next spring and I’d need to find a way to grow 5+ inches to get there by then. Has anyone found any techniques or products that have really helped them get fast growing hair? I should mention that I am vitamin D, B12, and Iron deficient and I’m working with a doctor to get those levels stable.
