This product here is great. It's very thick. It has a nice like soft crumbly texture. It's very shiny. The bottle was OK for what you ordered, but the product itself works great my sister has alopecia and I've used it consistently and saw results so this product is definitely about consistency. The more you use it the more results you see it does smell like a strong coffee so I don't know if you wanna walk around with this without your day. It does smell like coffee, but it is great so I suggest personally use the product. Let it sit on your hair if you're not going anywhere for the day leave it but if you're going somewhere wash it out use it as a treatment.
