“Love this brow serum. Have tried all and this is the best with no toxic chemicals. Brush is a little crunchy to start but will soften with time/use. This is a treatment oil- use sparingly if you have combo or oily skin so it won’t cause a blemish. Be patient. I saw some growth in my barely there brows and in places where I didn’t have any hair and hoping for more but not expecting miracles. I started experimenting with the oil on my lashes snd they are growing!”
