FREQUENTLY ASKED QUESTIONS
How does hair grow?
Your hair grows in a continuous cycle with four phases: 1. Anagen (Growing Phase): This is the active growth period, lasting 3-4 years. Most of your hair (85-90%) is usually in this phase. If you're experiencing hair loss, this growing period can become much shorter. 2. Catagen (Transition Phase): A short transitional stage (2-3 weeks) where hair growth* stops, and the hair follicle shrinks slightly. 3. Telogen (Resting Phase): The follicle takes a break (about 3 months) before the hair sheds. Normally, around 10-15% of your hair is in this resting phase. However, with hair loss, a larger percentage of hairs can enter this resting phase, leading to thinner-looking hair. 4. Exogen (Shedding Phase): This is the phase where the hair actually falls out (typically lasting 2-6 months). The follicle then prepares for a new hair to grow. It’s completely normal to shed some hairs
What are the common types of hair loss?
Here's a simplified look at two common types of hair loss: •Hereditary Hair Loss (Androgenetic Alopecia): This type of hair loss is gradual and often runs in families. It's caused by genetics or hormonal changes and unfortunately isn't reversible. It's more common in men, affecting 20% before age 20 and half of all men over 50. It also affects women, especially after menopause. •Temporary Hair Loss (Telogen Effluvium): This type of hair loss happens suddenly and can be quite intense, but the good news is that it's usually temporary. It can be triggered by stress, childbirth, seasonal changes, illness, tight hairstyles, or even dietary issues. Once the underlying cause is addressed, the hair typically grows back.
What causes hair loss?
Worried about your hair loss? You're not alone. Hair loss affectsover one third of Canada's adult population at some point. Here's a look at three key reasons why it happens: 1. Oxygen Imbalance: Healthy hair follicles need the right amount of oxygen. A protein called HIF-1 helps regulate this. But if HIF-1 isn't working properly, hair follicles do not receive enough oxygen, their metabolic activity can be impaired, leading to a decrease in the production of new hair strands, causing them to shrink and produce thinner hair. 2. Hardening Around the Follicle: L'Oréal research indicates that hair loss can be accompanied by a thickening of the cover around the hair follicle due to collagen buildup. This hardening restricts nutrient flow (microcirculation) to the hair. Consequently, the malnourished follicle produces thinner, weaker hair, which eventually falls out. 3. Environmental and Lifestyle Factors: Various external factors contribute to hair loss by increasing oxidative stress and damaging cells, thus affecting hair regeneration. These external factors include UV rays, pollution, inadequate diet or changes in weather and seasons can influence hair shedding.
How to combat hair loss?
While some types of hair loss are temporary and reversible, others require consistent care to manage. The L’Oréal Paris Hair Expertise Density Booster range is specifically designed to help combat signs of hair thinning and hair loss due to breakage, offering a complete routine that reinforces the hair fiber and helps prolong the hair life cycle. Formulated with Aminexil-R, a clinically studied molecule, the Density Booster system works to: •Strengthen hair from root to tip to reduce breakage, a common cause of hair fall. •Reinforce hair fiber for visibly denser, fuller-looking hair. •Prolong the hair’s life cycle, helping hair remain in the growth phase longer. Used daily, the shampoo and conditioner cleanse and nourish the scalp and lengths, while the Density Booster Serum penetrates the scalp with targeted care to support thicker-looking hair over time.
How often should I use the Density Booster routine?
For best results, use the Density Booster routine daily to strengthen hair and reduce fall, promoting thicker, fuller hair over time.
Is the Density Booster range suitable for all hair types?
Yes, whether your hair is curly, straight, color-treated or not, the Density Booster range is suitable for all hair types experiencing hair thinning and breakage-related hair loss.

Growth booster shampoo, please do a strand test
3 months ago
I had the worst experience ever with this shampoo. I was suffering of mild hair loss after surgery, they call it “telogen effluvium” that is normal and subsides with time. No bald poaches neither obvious hair loss only I noticed it in my house and clothes. I bought this shampoo and serum to help with this and ended up being worse than the actual mild hair loss.
I washed it in the shower and left it in a bun above my head a few minutes to let it work while I was showering my body. When I went to rinse it, it was a hard knot I couldn’t get comb through. I tried several conditioners(all elvive ones) without avail. I contacted L’Oréal and they did mention some people had experienced knotting. They advised me to soak the hair in warm water 30 minutes and use a detangler, which didn’t work. My hair was waist long and now I have a knot at the top of my head that I’m going to have to cut today as it’s impossible to dissolve this knotted bun. I filed a report with pictures in boots as I seriously think there should be a warning to do a stand test. I am not allergic to the hair growth component as Ive used their conditioner before with the same ingredient. I’ve read several people have suffered severe knotting and tangling if it happens to you, Please report it in the store (boots my case), they will send a report and help to get these warnings on the label so this doesn’t happen to others. I’m completely devastated, losing my hair and having to cut it short has affected my self esteem and mental health. I am broken, my hair was lovely and always got compliments from strangers, I don’t know how I’m going to cope with this.

I bought this hair conditioner to replace the blue conditioner for thicker hair that you have discontinued. I was very disappointed that it was discontinued as I found it beneficial. The growth booster conditioner has made my head itch and has brought my forehead out in an itchy rash .
