I've been using the hair multiplier for about 2 months now. The formula is excellent and I love how it absorbs quickly and doesn't leave my hair greasy. I've definitely noticed a healthier scalp compared to seasons past. My hair appears to be growing but I think it's a little too soon to tell. I will be reordering after my current order is over.

I have been using Le Jardin for a month and I especially started to use it around my temples. I noticed hair growth within weeks! What is now a bald spot has more of the fine baby hairs coming in. Its boosted my confidence as well. So happy and thankful for this product!

I’ve been using it for about four months now and while I’ve tried other serums that work, I think this is so far the fastest and has resulted in tons more baby hairs! I love it!! Will definitely keep using it!!
