About this study

In this study, the investigator will try to highlight the presence of carbonyl compounds in the hair follicles of postpartum women by comparing these compounds before and after delivery.

Read the detailed description

At the cutaneous level, oxidative stress induces the formation of carbonyl compounds which, by binding to proteins, produce non-functional adducts inducing cutaneous aging. This mechanism is called "carbonyl stress".

During pregnancy, estrogen increases massively, stimulates the whole body and prolongs the life of the hair (slower passage in telogen phase).

After delivery, estrogen levels drop, resulting in a massive and simultaneous hair loss that should have "naturally" fallen earlier. In addition, birth is a stressful stage for most moms. This stress and excessive fatigue and possibly a return to work may also be responsible for hair loss.

Is the carbonyl stress also present in the scalp and can it be one of the mechanisms involved in the occurrence of postpartum hair loss? To demonstrate this, samples of hair follicles are taken. The proteins are extracted from the samples and then assayed. The oxidized (carbonyl) proteins are labeled with specific fluorescent probes

Being tested
Hair follicles sampling

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Hair follicles samplingOther

    The hair follicles will be collected by strand of 5 to 6 hairs approximately in the scalp (centro-parietal part), in order to obtain 20 follicles with epithelial sheath.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change of biological evaluation

    Evaluation of the quantity of carbonyl compounds measured in the hair follicles taken before and after delivery.

    Measured: 1st sample: inclusion visit (up to 8 weeks before delivery)- 2nd sample: end of study visit (10 to 16 weeks after delivery)

Secondary outcomes (1)
  1. Safety evaluation

    Adverse events evaluation for all subjects, all along the study

    Measured: From inclusion to end of study

Questions about this trial

What is this clinical trial studying?

A study testing Hair follicles sampling in people with Telogen Effluvium, run by Pierre Fabre Dermo Cosmetique at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 May 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of biological evaluation (time frame: 1st sample: inclusion visit (up to 8 weeks before delivery)- 2nd sample: end of study visit (10 to 16 weeks after delivery)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 May 2020.
