Dreadlocks Journey Emotional Support
I agree on the biotin--research foods that have it and up those if you can to get it naturally. I'm getting married in August and currently my hair is half dreaded...it's kind of exciting not knowing how they'll look by then.
Can you use bobby pins at all? There are stronger holding ones at beauty supply shops like Sally's. I looked at your photos and I Iike the half up/down look on you. You could fasten that with a pretty barrette and your veil. Or find a flower wreath, fun headband, or blusher veil that suits your style and wear your hair down. Lastly, if your wedding is vintage at all, you could pin it up and find an awesome hat to wear. Hope that helps to spark some creativity!
