Not just baby hairs - it works!!
This review is long overdue but given the rate of natural hair growth I wanted to ensure it wasn't just fuzz, baby hairs, or wishful thinking. As you can see I also have some psoriasis on my scalp before I began and still. This product had no affect, neither positive or negative, on the psoriasis ...

DECIEM will not disclose content concentration
This product is in large part marketed on the fact that it contains REDENSYL. There's some clinical evidence that REDENSYL promotes hair growth. However, DECIEM will not disclose the concentration of REDENSYL in this product, making it impossible to compare with alternative products containing the i...

Excellent, I recommend it
It helped me a lot with my hair loss.
so good
I have been using this serum since over a year now and the results are amazing!! you have to be patient. I had so much hair fall after I got sick , used this serum for couple of months first and saw the result so I have been repurchasing this serum since then . I have seen some major new hair growth on my scalp, my scalp is way less visible then before, hair looks healthy and thick . My father also loves it so much , applies everyday and has also seen such great results with it . So it is dad approved also . Go for it!!
Slow process but well worth it
Alot of my hair had thinned out and seen most reviews were good for this product. Ive been using this product for 2ish months.. and definitely see it is working, when i part my hair in layers to style i see sprigs of new growth every where. I use more than the recommended drops normally filling the vile halfway up and using it in sections before going to bed.
1 bottle - visible results
I don't even use it everyday although I aim to but there is clear improvement in growth, density near the forehead and hair fallout. this is clearly a repurchase. I wish there was a better applicator. its a dropper but it's hard to get the last 2-3 applications
Beware if you have allergies
So I have bad juniper allergies which I didnt think would transfer to this product since it has larch trees but after four nights of use i noticed the same allergy symptoms i would have with my juniper allergies would be triggered by this product. I didn't want to score it lower because of my inability to use it to ding it too bad. If I am able to update at a later time I will once i find a friend who is able to use it instead so it doesn't get wasted.
