Individual results will always vary because our hair has its own natural growth cycle. With that being said if you use RbyNLash ® exactly as recommended, you will see stronger, thicker, longer-looking lashes in time. Consistency is always key. Some of our customers report seeing results as soon as 5 weeks into their bottle, while others saw results 9 weeks into it. Everyone’s lash growth cycle is different. RbyNLash ® is to be used to support your natural lash cycle which changes every 60-90 days.
