Personally, I was not satisfied with this product due to its duration. I cannot fully judge its effectiveness because I used it in combination with other products from the same line. However, what is certain is that it ran out within a month, using it twice a week, applying the product from the shoulders to the ends and not throughout the length of the hair.

Overall, my experience with the line:
After 1.5 months of using the olaplex line, I decided to share my experience. I have long, wavy to curly, relatively dry hair with highlights. I purchased the [No 0+3+4+5+6+7+8] line after completing steps 1+2 at the salon. I used No 0+3+8+4+5 twice a week and 6+7 on a daily basis. The reason I chose to buy the line was because I had highlights on my hair [which was previously completely healthy] and my hair was greatly damaged [to the point where the wet ends would melt and break]. So, shocked and after conducting some research, I ended up with olaplex, which I started using immediately after the salon, where I had the highlights done.

I cannot judge the current condition of my hair if I did not use this line because I started using it immediately after the salon. However, I will mention some things I noticed. Indeed, after applying No 3 and the rest of the steps, my hair was noticeably softer. However, this softness lasted for a few hours and not days, at least for me, as my hair tends to become dry.

Regarding the ends of my hair, I gradually noticed a significant strengthening [in the beginning, the wet hair was so elastic that it would break or melt immediately, but now it has become stronger].

As for hair breakage and split ends, I did not notice any significant improvement. The truth is that even with the use of the line, many strands still broke at the ends, resulting in uneven lengths.

Furthermore, I did not notice any change in the shine of my hair or frizz.

I believe that the line helped in restoring the ends by strengthening the hair to a satisfactory extent, preventing future damage, but this does not mean that it is a miraculous product that transformed my damaged hair and fully maintained its length. Therefore, I think it helps prevent further damage to the hair, which is also important. However, its price is definitely discouraging. Additionally, another issue is the duration of the products. No 3, 4, 5, 6, and 8 ran out after 1.5 months of using them twice a week, and considering their cost, it is quite an expensive line. On the other hand, products 0 and 7 have a much longer duration.

In conclusion, it is a commendable line in terms of restoring hair bonds, but due to its price and the lifespan of the products, I would only purchase it if my hair was extremely damaged, making this treatment the only option.

Positives:
- Strengthening of hair
- Filling of ends
- Nice scent
- Prevention of future damage

Negatives:
- Price
- Duration of products
